Abstract

This research article presented the development of a T-Source inverter controlled by Unipolar pulse width modulation (PWM) for boost voltage levels. The aim was to study, design, and develop a T-Source inverter circuit that could step up DC voltage and convert it to AC voltage in a single stage. The developed circuit included two inductors, one capacitor, and fast recovery diodes along with a full-bridge inverter, which reduced the number of components compared to a Z-Source inverter. The switch control used Unipolar PWM through a C2000 series TMS320F28379D microcontroller. The design and operation were first simulated using MATLAB/Simulink before developing the actual prototype. Experimental results showed that the circuit could efficiently increase the voltage from an input of 100 volts to an output of 200 volts under both linear and inductive load conditions. In addition, the output voltage waveform was close to a sine wave, and the experimental results tended to match the simulation results. The developed circuit could be applied in power conversion work and power electronics systems that required appropriate voltage boosting.
