Abstract
The present disclosure provides a power converting method for high frequency inverter and low frequency inverter connecting in parallel, which includes the flowing steps. Provides a low frequency inverter module electrically connected to a DC power. Provides a high frequency inverter module connected in parallel with the low frequency inverter module. Adjust a high frequency switching duty ratio of the high frequency inverter module to output a second current according to a first current from the low frequency inverter module. The second current is for compensating ripples of the first current. Therefore, the ripples of the first current of the low frequency inverter module can be compensated by the high frequency inverter module.
