Abstract
Power supplies are known, in particular power supplies under primary clock-pulse control, that comprise a closed housing for the primary and secondary circuits, and a forced-air cooling means to cool the heat-producing components of the circuits. A power supply is proposed in which additionally there is a ventilation conduit in communication with the air outside the housing to serve as a cooling medium. The cooling means also comprises at least one cooling-unit element, on which the heat-producing components are mounted, and a portion of said element projects into the ventilation conduit and is electrically isolated by insulating means.
