飞跨电容多电平变换器实际应用中的电容电压平衡研究

Capacitor voltage natural balancing is an attractive feature of flying capacitor multilevel (FCML) converters. However, with the commonly used phase-shifted pulsewidth modulation, the capacitor voltages still can deviate, and active balancing is often required. Although the natural balancing mechanism and its dynamics have been extensively studied in existing literature, some sources that are resp...
