Abstract
A power conversion system may include a plurality of power devices and a sensor operably coupled to at least one of the plurality of power devices and configured to detect a voltage, current, or electromagnetic signature signal associated with the plurality of power devices. The power converter may also include circuitry operably coupled to the plurality of power devices and the sensor. The circuitry may send a respective gate signal to each respective power device of the plurality of power devices, such that each respective gate signal is delayed by a respective compensation delay that is determined for the respective power device based on a respective time delay of the respective power device and a maximum time delay of the plurality of power devices.
