Rectifiers are widely use in areas of industry and commerce to implement equipment which require to be powered by alternating current (AC) source, so that uncontrolled rectification requires an operational requirement study because they only properly works if the rectifier calculated boundary conditions are ideal and invariant. Therefore the implementation of control strategies should be take into account to generate the desired signal performance in the rectifier. This document shows the implementation of different control techniques on the behavior the sinusoidal current in a single-phase rectifier width modulated pulse and resistive load. Consequently, in this work the development of several control strategies are presented, for behavior analysis of signals in a rectifier with width pulse modulation and resistive load. Additionally, a comparison between the developed controllers is performed in order to get the best behavior available for this applications.

This paper proposes three Carrier Overlapping PWM (COPWM) methods that utilize the (CFD) control freedom degree of vertical offsets among carriers. They are: COPWM-A, COPWM-B, COPWM-C these three methods are simulated . This paper presents a comparative study of diode clamped and cascaded three phase five-level inverters based on sinusoidal PWM& modified space vector PWM control techniques. Performance analysis is based on the results of simulation study conducted on the operation of the multilevel inverters using MATLAB/ SIMULINK. For comparison purposes, non-overlapping phase disposition PWM (PD PWM) using SPWM and modified space vector PWM is also presented. The performance parameters chosen the work included fundamental output voltage and total harmonic distortion. . A hardware set up was developed for a single-phase 5-level cascaded inverter topology using constant pulses.

Control Scheme

In this paper, an improved load sharing control scheme is presented, which is able to improve the transient response and power sharing accuracy of parallel-connected inverters used in microgrid. It also shows how the improved droop method can be easily adapted to account for the operation of parallel-connected inverters, providing good performance under the variation and disturbance of loads, as well as achieving good steady-state objectives and transient performance. Two DSP-based single-phase Microgrid inverters are designed and implemented. Simulation and experimental results are all reported, confirming the validity of the proposed control technique.
