An AC powered source usually has a significant level (often several volts) of line frequency commonmodevoltage.
交流供电的源通常具有很高电平的电源频率共模电压(常常有几伏)。

The algorithm yields low commonmodevoltage and current, acceptable PWM ripple at the input and output of the inverter, and has no overvoltage problems unlike AZSPWM1.
It is important to ensure that the total cell voltage across the string does not exceed the commonmodevoltage rating and the maximum voltage level of the switch module.
