ABSTRACT:
A high voltage semiconductor valve has a plurality of electrically series-connected semiconductor elements, for example thyristors or diodes. These are designed for pressure contact connection and for double-sided cooling and are arranged alternately with liquid cooling bodies in a stack. At least some of the resistors included in the voltage divider of the valve are arranged with their resistive portions located in a passage in the cooling body between the contact surfaces for the two adjacent semiconductor elements.
