TLDR
In this article, a three-level adaptive hysteresis band modulation strategy for single-phase inverters is presented, which can be defined using a modulation process possessing both pulse-width and pulse-position modulation.Abstract:
A novel three-level adaptive hysteresis band modulation strategy for single-phase inverters is presented. It is shown that the total harmonic current distortion of the new strategy closely approximates that of the off-line precalculated harmonic minimised PWM switching angle solution sets. It is shown that the three-level adaptive hysteresis band strategy can be defined using a modulation process possessing both pulse-width and pulse-position modulation. Two strategies are presented to determine the switching angles in one quarter of the fundamental period of the PWM and the advantages of each method are discussed using a digital signal processor implementation. Both simulation and experimental results for the three-level adaptive hysteresis band PWM strategy are presented to confirm the theoretical analysis.read more

A PWM method for reduction of switching loss in a full-bridge inverter
Ray-Shyang Lai,Khai D. T. Ngo +1 more
TL;DR: In this article, a hybrid pulsewidth modulation (HPWM) method was proposed, which requires only two of the four switches in a full-bridge inverter to be pulsewidth-modulated at high frequency, thus reducing the switching losses in the other two switches.
