一种主开关电流应力较低的并联谐振直流环节逆变器

The resonant current of the resonant dc link inverter is superimposed on the main switch in periods of the zero-voltage notch creation, which increases the current stress as well as the conduction loss of the main switch, and inevitably escalates the selection cost of the main circuit. To solve these problems, a parallel resonant dc link inverter with low current stress on main switch is proposed ...
