Paper Sharing: Abnormal Voltage Compensation caused by Vertical Crossing in Phase-shifted PWM-based Cascaded H-bridge Inverters
The paper presents a compensation method for abnormal voltage generation in phase-shifted PWM-based cascaded H-bridge inverters caused by vertical crossing. Vertical crossing, which leads to missed PWM pulse updates and subsequent voltage errors and current surges, is predicted by analyzing the modulation wave and carrier slope at every sampling instance. The proposed approach adjusts the modulation wave in the
