Abstract

A semiconductor element, either a diode or a controlled rectifier, is electrically insulated relative to the heat sink on which it is mounted by either an insulating layer or an insulating diode of high thermal conductivity. A single unit including the heat sink with a plurality of diodes is used as a bridge rectifier in single phase or polyphase circuits.
