Abstract

A pulse inverter includes a pulse inverter housing, in which at least one power electronics is provided, wherein at least the pulse inverter housing is configured to be cooled by a flowing coolant through housing means. The power electronics includes at least one controller, a gate driver, and a semiconductor element. For switching a semiconductor element, the gate driver provides a turn-on voltage UGS and a turn-off voltage U0 and is actuatable by the controller for this purpose. The controller includes control means, via which a withstand voltage UR<UGS is adjustable, whereby a power dissipation PV can be generated, causing the power electronics and/or the coolant to heat up.
