  • Patent number: 11336206
    Abstract: Methods, non-transitory computer readable mediums, and power conversion systems with a controller configured to provide modulated inverter switching control signals at a first switching frequency in response to an inverter current being greater than a first threshold and less than a second threshold, the second threshold being greater than the first threshold. The controller is further configured to provide the inverter switching control signals at a second switching frequency in response to the inverter current being greater than the second threshold, and to provide the inverter switching control signals at a third switching frequency in response to the inverter current being less than the first threshold, where the second switching frequency is less than the first switching frequency and the third switching frequency is greater than the first switching frequency.
