摘要
This paper presents the ''hybrid pulsewidth modulation'' (HPWM) method which requires only two of the four switches in a full-bridge inverter to be pulsewidth-modulated at high frequency, thus significantly reducing the switching losses in the other two switches, For triangular carriers, HPWM has the same frequency spectrum and switching losses as the conventional unipolar PWM (UPWM), A low-frequency model for a fast-switching HPWM full-bridge inverter with high-quality output is described, and is substantiated by experimental data.
