“…A voltage limiter calculation method for fast torque response of an interior PMSM (IPMSM) when an inverter operates in the over-modulation range has been analysed (Lerdudomsak, Doki, & Okuma, 2010). An all-digital concept with sinusoidal variation for SPWM generation has been proposed, and the harmonic distortion maintains less than 1% (Ngalamou & Myers, 2008). The development and applications of harmonic injection technique have been reviewed.…”

In a permanent magnet synchronous motor (PMSM) control system, usually, the phase voltage instruction is limited independently to prevent a three-phase pulse width modulation (PWM) wave from overflowing. This method decreases the efficiency of the bus voltage and causes voltage vector direction errors. To solve these problems, we propose a harmonic injection sinusoidal pulse-width modulation (SPWM). This method uses harmonic injected sinusoidal PWM to improve the utilisation ratio of the bus voltage, and consequently improve system performance. In this paper, we analyse the problem in terms of potential difference. The simulation results show that the proposed method can increase the utilisation ratio of the bus voltage up to 15.4%, and the voltage vector mode obtained with the proposed algorithm is larger than that obtained with the conventional one. The method with harmonic injection consequently improves current response, without affecting voltage vector accuracy. The experiment results validate the proposed method.

“…These traditional SPWM methods suffer from shortcomings like high total harmonic distortion (THD), high switching losses etc. A modified SPWM method is presented in [10] to reduce the THD value of the SPWM method.…”

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.
