Abstract
Various embodiments include a circuit arrangement for controlling a power semiconductor switch including a gate terminal, a source terminal, a drain terminal, and a conduction channel between the source and drain terminals, comprising: a controller for generating a control signal to alternate the semiconductor switch between a turned-on state and a turned-off state; a current source for injecting a current into the gate terminal; and an evaluation unit. The evaluation unit measures a voltage between the gate terminal and one of the source terminal and drain terminal while the semiconductor switch is in the turned-on state; and determines from the measured voltage and the current an absolute temperature of the semiconductor switch.
