| Popis: | This article presents a design and implementation of four switch inverter (FSI) for micro-grid application. The main benefit of the designed inverter has flexibility in design, simple control, minimal cost as well as less space. It is appropriate for medium and high power applications. The designed inverter has produced pure sinusoidal output voltage waveform with help of pulse width modulation (PWM) control scheme which leads to decrease the total harmonic distortion (THD) of it. For designing the inverter with help of the switches, this is directly related to their voltage drops and also, this switching voltage drops has increases the overall loss of this system. The Efficiency of the system is decreased due to this high overall converter loss. In order to increase the efficiency, reduce the switches and the switching losses, FSI is developed. The structure of the FSI is a combination of the push-pull and the synchronous buck converters. The performance of the complete model is investigated at different operating stages by making the MATLAB/Simulink models. The simulation results are presented to show the efficacy of the designed inverter. |
