“…For off-grid and grid-connected systems, single-phase (half-bridge and full-bridge) or three-phase inverters are used depending on the load requirements. Single-phase full-bridge inverters are commonly used in integrated rooftop PV systems [2]. Electric vehicle/hybrid electric vehicle (EV/HEV) and uninterruptible power supply (UPS) systems also require inverter circuits.…”

This paper examines several sinusoidal pulse-width modulation (SPWM) methods for single-phase H-Bridge inverters. Various SPWM strategies have been proposed in the literature up to this point. With PWM, the inverter’s output voltage can be changed, so large filters are no longer needed. The conventional and modified SPWM techniques are described in this paper. Total Harmonic Distortion (THD), switching losses, fundamental component values, and dead time losses are used to compare the effectiveness of these SPWM methods. A MOSFET-based H-bridge inverter circuit is developed to verify different SPWM methods. The design of a transformer-based filter circuit for a single-phase H-bridge inverter is also included in this study. The hardware implementation uses the Delfino TMS320F28379d digital signal processor (DSP). This article explains how to integrate MATLAB-Simulink with the TMS320F28379D DSP processor. The hardware results, as well as the programming approach, are presented in this paper.
