ABSTRACT:
An enclosure or cabinet is provided for single phase rectifiers that has a very low profile, low noise, efficient cooling, low temperature rise, and which is competitive with switch-mode technology rectifiers. The rack includes a chassis which is very strong and that has a horizontal base and a rear vertical wall secured to each other, and all of the components are mounted to the base or rear wall, or to components already mounted, with the single exception of a supervisory control panel which is mounted on the door panel that has been hinged to the front edge of the base. Light-weight sheet metal side walls and cabinet cover may be formed as a hood and placed over the assembled components to close the enclosure. A UI transformer and an EI saturable reactor are each mounted to the rear wall of the chassis, one above the other, and are wound in such a way that adequate air spaces exist between the coils on the core legs. Generally the UI transformer is also supported from the base. Cooling slots are formed in the horizontal base and vertical rear wall, in the cabinet side walls, and may also be formed in the cabinet top cover. All electrical connections are made at the front of the cabinet, thereby assuring easier assembly, using less material and with less chance for mistakes to be made.
