In this paper, a single phase dc to ac inverter with a low cost driver circuit was developed. The input source is a battery tank of four series-connected LiFePO4 batteries. The input DC power is then converted into the output AC power with 110Vrms and 60Hz. The proposed inverter is composed of a boost DC converter and a full bridge inverter. As for the circuit architecture, the boost converter is used to boost the battery tank voltage to 190V DC voltage bus. The DC voltage bus is then used to generate the output AC voltage by the full bridge inverter. A low price micro-controller unit HT66F50 was adopted for the controller of the proposed inverter. Moreover, instead of a common switch driver IC, a driver circuit with about 50% cost reduced was constructed for the full bridge inverter. A prototype with 300W rated output power was practically constructed and it can be seen that the total harmonic distortion is lower than 5%.

Inverter Topology

Multilevel inverter (MLI) has become more popular in high power, high voltage industries owing to its high quality output voltage waveform. This paper proposes a novel single phase extendable type MLI topology. The term ‘extendable’ is included since the presented topology can be extended with maximum number of dc voltage sources to synthesize larger output levels. This topology can be operated in both symmetrical and asymmetrical conditions. The major advantages of the proposed inverter topology include minimum switching components, reduced gate driver circuits, less harmonic distortion and reduced switching losses. The comparative analysis based on the number of switches, dc voltage sources and conduction switches between the proposed topology and other existing topologies is presented in this paper. The comparison results show that the proposed inverter topology requires fewer components. The performance of the proposed MLI topology has been analyzed in both symmetrical and asymmetrical conditions. The simulation model is developed using MATLAB/SIMULINK software to verify the performance of the proposed inverter topology and also the feasibility of the presented topology during the symmetrical condition has been validated experimentally.

This paper presents a single-phase multilevel inverter (MLI) with simpler basic unit cells. The proposed MLI is able to operate in two modes, i.e. charge mode to charge the batteries, and inverter mode to supply AC power to load, and therefore, it is inherently suitable for photovoltaic (PV) power generation applications. The proposed MLI requires lower number of power MOSFETs and gate driver units, which will translate into higher cost saving and better system reliability. The power MOSFETs in the basic unit cells and H-bridge module are switched at near fundamental frequency, i.e. 100 Hz and 50 Hz, respectively, resulting in lower switching losses. For low total harmonic distortion (THD) operation, a deep scanning method is employed to calculate the switching angles of the MLI. The lowest THD obtained is 8.91% at modulation index of 0.82. The performance of the proposed MLI (9-level) has been simulated and evaluated experimentally. The simulation and experimental results are in good agreement and this confirms that the proposed MLI is able to produce an AC output voltage with low THD.

Abstract In this paper, a single-phase switched boost inverter is proposed. Dividing converted sources is a very popular technique in recent years, as well as the demand for high output voltage quality by the use of a small number of switches. The analysis and simulation study revealed that this inverter has a good potential in terms of conversion quality (high voltage gain, low total harmonic distortion (THD), low cost, simple structure, and easy to control) and can be used in photovoltaic applications as well as in embedded systems. Experimental results verify the functioning principle of the presented topology but this new topology needs more improvements to reach exactly the simulation results.

Now day’s the power factor has become a major problem in power system to improve the power quality of the grid, as power factor is affected on the grid due to the nonlinear loads connected to it. Single phase bridgeless AC/DC power factor correction (PFC) topology to improve the power factor as well as the total harmonic distortion (THD) of the utility grid is proposed. By removing the input bridge in conventional PFC converters, the control circuit is simplified; the total harmonics distortion (THD) and power factor (PF) are improved. The PI controller operates in two loops one is the outer control loop which calculates the reference current through LC filter and signal processing. Inner current loop generates PWM switching signals through the PI controller. The output of the proposed PFC topology is verified for prototype using MATLAB circuit simulations. The experimental system is developed, and the simulation results are obtained.

Cascaded Multilevel Inverter

In this paper, a new topology for cascaded multilevel inverters based on quasi Z-source converter is proposed. In the proposed topology, the magnitude of output voltage is not limited to dc voltage source, while the magnitude of output voltage of conventional cascaded multilevel inverters is limited to dc voltage source. In the proposed topology, the magnitude of output voltage can be increased by controlling the duty cycle of shoot-through (ST) state, transformer turn ratio, and the number of switched inductors in the Z-source network. As a result, there is no need for extra dc–dc converter. In the proposed topology, the total harmonic distortion (THD) is decreased in comparison with the conventional Z-source inverters. The proposed topology directly delivers power from a power source to load. In addition, in the proposed basic unit, higher voltage gain is achieved in higher modulation index which is an advantage for the proposed base unit. The performance of the proposed topology is verified by the experimental results of five-level single-phase inverter.

This paper presents the use of a single-phase voltage-doubler Boost rectifier, to generate a controlled DC voltage, which is applied to a four-quadrant chopper. The transistor chopper controls the speed of a separately excited DC machine. The Boost rectifier permits the regeneration of energy from the motor to the single-phase mains, maintaining in all operating points a practically sinusoidal input current, with a THD of 2.5%. The balancing of the two filter capacitors is achieved by using and additional control loop. A low cost microcontroller is used to control the DC voltage and the motor speed.

<p class="Abstract"><span lang="EN-US">Across the year, the needs of Indonesians in the use of electronic equipment are increasing, which results in higher electricity usage. Because most of the electricity load uses AC power, in the application of a DC power source such as solar cells, an inverter that converts DC to AC power is needed. Therefore, the inverter is one of the tools that are widely developed in power electronics. The output voltage from simulation and real hardware is a sine wave with some distortion due to lack of filter; therefore, there occurs a harmonic. The voltage and frequency were also measured with a multimeter. The result shows that both voltage and frequency are closed to the design specification which is 220V 50Hz with the voltage and frequency difference of 1.09% and 0.4%, respectively.</span></p>

In this work, DC and AC parts of hybrid microgrids are interconnected by a neutral point clamped—NPC converter controlled using a new backstepping predictive (BP) method. The NPC converter is controlled to operate in the DC microgrid voltage control mode or in the AC microgrid power control mode. The novel backstepping predictive controller is designed using the dq state space dynamic model of the NPC converter connected to the hybrid microgrid. The designed BP controller regulates the DC voltage or AC injected power, balances the capacitor voltages, controls the AC currents, and enforces the near unity power factor. Simulation (MATLAB/Simulink) and experimental (laboratory prototype) results show that the converter can regulate the DC voltage in the DC microgrid interconnection point, by adjusting the AC power conversion to compensate variations on the loads or on the distributed renewable energy sources in the DC microgrid. AC currents are sinusoidal with low harmonic distortion. The obtained BP controller is faster at balancing capacitor voltages than PWM (pulse width modulation) control with carrier offset. The fast AC power response allows the converter to be used as a primary frequency regulator of the AC microgrid. This research is appropriate for power and voltage control in hybrid microgrids with renewable energy.
