摘要： A power conversion system includes a power converter having output terminals that are electrically isolated from input terminals. The power conversion system further includes a circuit configured to couple a voltage input from a power source to the input terminals, and provide an output voltage to a load that is a series combination of the voltage input and a voltage across the output terminals.

摘要： A powertrain includes a first and second switch coupled in parallel to drive an electric machine and a gate driver. The gate driver may be configured to, in response to a transition request while a first temperature of the first switch exceeds a second temperature of the second switch, inject a current onto a gate of the second switch to drive rates of change of current through the first and second switch to the electric machine to a same value.

摘要： A voltage converter includes a switch having a switching loss that decreases as a switching frequency of the switch decreases. The voltage converter further includes a controller programmed to vary the switching frequency based on a duty cycle of the switch and a current input to the switch to reduce switching losses or reduce a ripple current magnitude.
