Abstract
A power module having at least one power transistor. Each power transistor is coupled to and protected by an overvoltage clamp and desaturation detection circuit. An output current measurement system is coupled to the power module output. A junction temperature sensor is coupled to each power transistor. An isolation transformer is associated with each power transistor, the primary windings of which are connected to an isolated driver communications interface which converts logic signals to primary winding drive signals. An isolated gate driver is coupled to the secondary winding of each isolation transformer and the gate terminal of each power transistor.
