级联H桥逆变器中通过反映电流极性比例抑制过零畸变的死区补偿方法

This letter proposes an enhanced dead-time compensation method in cascaded H-bridge (CHB) inverters to mitigate current zero-crossing distortion (ZCD) by reflecting the ratio of current polarity. Typically, dead-time compensation involves adding an offset voltage, whose sign is determined by the current polarity, to the switching reference voltage. However, in digital signal processor (DSP)–based ...
