  • Power converting device and method with high-frequency inverter module compensating low-frequency inverter module
    Patent number: 11056983
    Abstract: A power converting device with a high frequency inverter module compensating a low frequency inverter module is for transmitting a direct current voltage to an alternating current load module. The low frequency inverter module is controlled by a low frequency duty ratio. The high frequency inverter module is connected to the low frequency inverter module in parallel and controlled by a high frequency duty ratio. The low frequency inverter module is controlled according to the low frequency duty ratio to generate a first current. The high frequency duty ratio is adjusted according to a low-frequency ripple current. The high frequency inverter module is controlled according to the high frequency duty ratio to generate a second current, and the second current is for compensating ripples of the first current.
