A DC to DC converter has been built and research has been conducted to examine the effect of load on the output voltage of the DC to DC converter with fixed oscillation frequency. This converter DC to DC circuit uses a 12 V DC battery as an input voltage source connected with a step-up transformer until it is successfully raised to 380 V DC. The load given to the DC to DC circuit converter in the form of lamps, varies from 40 watts to 960 watts with a fixed oscillation frequency of 65 Khz that has been determined by the microcontroller. The test results showed that the output voltage value decreased in accordance with the increase in load so that when the load of 960 watts obtained the output voltage of 220 V DC.

The grid-connected inverters required for distributed generation systems should have high reliability. However, a shoot-through problem, which is a major killer of the reliability of the inverters, exists in the conventional bridge-type voltage-source inverters. In order to solve the aforementioned problem, a non-isolated buck-boost grid-connected inverter with no shoot-through problem is proposed. The hysteresis current control is used. The output voltage of the proposed grid-connected inverter can be larger or lower than the input voltage. The operating principle is illustrated. Simulation verifies the theoretical analysis.

Ripple Reduction

In order to achieve a good dynamical response of a full-bridge AC-DC voltage source converters (VSC). The bandwidth of PI controller must be relatively wide. This leads to the voltage ripple produced in the control signal, as known that its ripple frequency has twice of the line frequency and cause the 3rd harmonic of an input current. A Ripple Voltage Estimator (RVE) algorithm and Feed-Forward Compensation (FFC) algorithm are proposed and added to the conventional control. The RVE algorithm estimated the ripple signal to subtract it occurring in the voltage loop. As a result, the 3rd harmonic of the input current can be reduced, and hence the Total Harmonic Distortion of input current (THDi) are improved.  In addition, the FFC algorithm will offer a better dynamical response of output voltage. The performance evaluation was conducted through the simulation and experiment at 110Vrms/50Hz of the input voltage, with a 600 W load and 250 V<sub>dc</sub> output voltage. The overall system performances are obtained as follows: the power factor at the full load is higher 0.98, the harmonic distortion at AC input power source of the converter is under control in IEC61000-3-2 class A limit, and the overall efficiency is greater than 85%.

Direct current (dc) voltage sources are one of the voltage sources most widely used for various purposes. Dc voltage can be obtained from a dc generator or by converting an ac voltage into a dc voltage using a power converter. There are several dc voltage levels that are commonly used by electrical and electronic equipment. To get a dc voltage that can be used for various equipment, then a dc voltage source must be varied according to the required. One way to get a variable dc voltage is to use a dc-dc converter. This research proposes a dc-dc boost converter that can increase the dc voltage with varying outputs. The boost converter is proposed using Arduino Uno as a controller with an input voltage of 12 volts. The converter output voltage regulation is implemented through Arduino programming using Matlab simulink. The experimental results show that the boost converter designed in this study has worked well as intended. This can be seen from the boost converter output voltage which is in accordance with the reference voltage entered in the Matlab simulink program

An 11-level switched-capacitor multilevel inverter (SCMLI) with 2.5 times boosting feature is presented in this paper. It can produce an 11-level output voltage waveform by utilizing 14 switches, 3 capacitors, 2 diodes, and 1 DC source. Only nine driver circuits are needed as the topology has three pairs of complementary switches and two bidirectional switches. It has inherent capacitor self-balancing property as the capacitors are connected across the DC voltage source during several states within a fundamental cycle to charge the capacitors to the input voltage. A detailed comparison shows the effectiveness of the proposed topology in terms of the number of switches, number of capacitors, number of sources, total standing voltage (TSV), efficiency, and boosting ability with the state-of-art recently proposed circuits. Subsequently, the performance of the proposed SCMLI is validated experimentally utilizing the nearest level control (NLC), a fundamental frequency-based switching technique.

Estos requisitos se cumplen con un inversor de fuente de voltaje (VSI). Se puede lograr un voltaje de salida variable variando la tensión de CC de entrada y manteniendo constante la ganancia del inversor. Por otro lado, si la tensión de entrada CC es fija y no es controlable, se puede lograr una tensión de salida variable variando la ganancia del inversor, lo que normalmente se logra mediante el control de modulación por ancho de pulso dentro del inversor. Hay varias técnicas de modulación de ancho de pulso, pero la técnica de vector espacial es una buena opción entre todas las técnicas para controlar el inversor de fuente de voltaje. La modulación por ancho de pulso de vector espacial (SVPWM) es un método avanzado y muy popular con varias ventajas tales como la utilización efectiva del bus de CC, menos generación de armónicos en voltaje de salida, menos pérdidas de conmutación, amplio rango de modulación lineal, etc. En este documento, se ha tomado un inversor de fuente de voltaje constante CC y se ha implementado la SVPWM para VSI de dos niveles utilizando MATLAB / SIMULINK. Descriptores: Modulación de ancho de pulso (PWM), modulación de ancho de pulso de vector espacial (SVPWM), distorsión armónica total (THD), inversor de fuente de voltaje (VSI). Abstract Alternating Current (AC) loads require variable voltage and variable frequency. These requirements are met by a voltage supply inverter (VSI). A variable output voltage can be achieved by varying the input DC voltage and keeping the inverter gain constant. On the other hand, if the DC input voltage is fixed and not controllable, a variable output voltage can be achieved by varying the gain of the inverter, which is normally achieved by controlling the pulse width modulation within the inverter. There are several pulse width modulation techniques, but the spatial vector technique is a good choice among all the techniques for controlling the voltage source inverter. Spatial vector pulse width modulation (SVPWM) is an advanced and very popular method with several advantages such as effective utilization of CC bus, less harmonic generation in output voltage, less switching losses, wide range of linear modulation, etc. In this document, a CC constant voltage source inverter has been taken and SVPWM has been implemented for two-level VSI using MATLAB / SIMULINK.

This paper presents a new ideology called as boost inverter which converts input DC supply into AC directly without using any filter circuit. The main part of today’s research work is to use solar energy efficiently. While using for AC autonomous loads, the output from the solar panel should not suffer any losses during the various power conversion stages. The conventional voltage source inverter, which is currently in usage, produces an AC output voltage lower than the DC input supply and thus it requires another power conversion stage. It can be used to drive the loads only after removing the ripples using a filter. The main objective of the project is to produce an AC output voltage higher than the DC input voltage in a single stage. Thus the number of power conversion stages is reduced by using boost inverter circuit. Since Pulse Width Modulation technique is used to drive the circuit, the requirement of a filter at the output is not needed

Splitting of a dc voltage source with two capacitors has been the approach in generating 5-level output voltage with single- and three-phase full-bridge circuits and added bidirectional switch. Associated with this configuration is the problem of voltage imbalance between the splitting capacitors. In addition, the inverter output voltage magnitude is obviously limited to the value of the split input voltage source. Presented in this paper is a unit topology for single-phase 5-level multilevel inverter, MLI. It simply consists of a full-bridge circuit, a capacitor, charge-discharge unit and a dc source. The charge-discharge unit with the capacitor is the interface between the full-bridge and the dc source. The proposed unit cell can generate a 5-level output voltage waveform whose peak value is twice the input voltage value. For higher output voltage level, a cascaded structure of the developed unit cell is presented. Comparing the proposed inverter with CHB inverter and some recent developed MLI topologies, it is found that the proposed inverter configuration generates higher output voltage value, at reduced component-count, than other topologies, for a specified number of dc input voltages. For two cascaded modules, simulation and experimental verifications are carried out on the proposed inverter topology for an R-L load.

<span>In this paper, a design and control for the buck-boost converter, i.e., 1-plus-D converter with a positive output voltage, is presented, which combines the 1-plus-D converter and the synchronous rectified (SR) buck converter. By doing so, the problem in voltage bucking of the 1-plus-D converter can be solved, thereby increasing the application capability of the 1-plus-D converter. Since such a converter operates in continuous conduction mode inherently, it possesses the nonpulsating output current, thereby not only decreasing the current stress on the output capacitor but also reducing the output voltage ripple. Above all, both the 1-plus-D converter and the SR buck converter, combined into a buck–boost converter with no right-half plane zero, use the same power switches, thereby causing the required circuit to be compact and the corresponding cost to be down. Furthermore, during the magnetization period, the input voltage of the 1-plus-D converter comes from the input voltage source, whereas during the demagnetization period, the input voltage of the 1-plus-D converter comes from the output voltage of the SR buck converter.</span>
