SELF-BALANCING PARALLEL POWER DEVICES WITH A TEMPERATURE COMPENSATED GATE DRIVER

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.
