Abstract

A semi-conductor power rectifier is esp. for use in the control circuitry of electrically powered trains. The rectifier is cooled using a refrigerant liquid such that distortion effects are minimised as is the need for pressure on the semi-conductor disc to maintain adequate electrical contact. The system allows an increase in the rectifier current capacity. The semi-conductor is in the form of the disc of passivated silicon held between two copper blocks. The blocks (3) are drilled out providing cooling channels (13, 14) across the semi-conductor-copper interface and axially (15, 16) through the blocks. The axial channels turns through an angle to emerge (17) from the block sides to connect with the surrounding volume of the rectifier.
