Abstract: A method and apparatus are provided for a power semiconductor switch. A current through the switch is responsive to a control terminal voltage at a control terminal of the switch, and the control terminal voltage is driven by a driver unit. The method includes measuring or estimating the current based on a bond voltage of the switch, detecting a short circuit by comparing the measured or estimated current to a short circuit current limit, controlling an on-state voltage level of the control terminal voltage based on the comparison to limit the current through the switch during the short circuit, and controlling the control terminal voltage to an off-state voltage level to turn the switch off. The on-state voltage level voltage is controlled by pulse-width modulating the output of the driver unit. A switching frequency of the modulation is at least the cut-off frequency of low-pass characteristics of the control terminal.

Abstract: A converter circuit with short-circuit protection can include a plurality of phase legs having a series connection of normally-on switches, between voltage rails of a DC voltage link, a DC link capacitor, and AC voltage connection points between the normally-on switches. A phase-to-phase short-circuit protection circuit includes a parallel connection of a resistive component and a controllable switch. The phase-to-phase short-circuit protection circuit including a first terminal connected to an AC voltage connection point and a second terminal forms an input or an output of the converter circuit; and a controllable switch is connected in series with the DC link capacitor. Upon lack of control of the normally-on switches the controllable switch of the at least one phase-to-phase short-circuit protection circuit and the controllable switch of the phase leg short-circuit protection circuit are adapted to be controlled to a non-conductive state.
