Abstract
This paper presents the design and implementation of the two-input impedance inverter circuit by using PWM modulation. The PWM modulation properties’ had the ability to reduce as well as increase the AC voltage on the output side without using a complicated voltage of compounding circuits, and also had the ability to reduce interference from electromagnetic. The gate drive did not need a dead-time loop, so there was no power loss during the time. The control circuit can be simplified by using an inverter circuit that increases the impedance network circuit, which consisted of inductors and capacitors of the same size crossed on the input side of a full-bridge inverter circuit. The circuit implementation was applied by the simulation’s operation of a single-phase inverter using the program MATLAB/Simulink, controlled the operation with PWM signal using Arduino MEGA 2560 board that modified to increase the short-circuit time from the original form of the voltage source inverter circuit. The simulation showed that the new inverter circuit can increase the AC voltage level on the output side without using a voltage compounding circuit and suitable for use with renewable energy sources.
