Abstract
Abstract A modular power supply for converting three-phase alternating to direct current for high power applications. A plurality of individual rectifying modules are all fed through a common threephase SCR controller. Each module in turn comprises its own transformer and rectifying circuit and has associated therewith an individual circuit breaker and cooling fan. The DC output from each module is collected by a common bussing arrangement and a particular automatic voltage-current regulator is provided to control the duty cycle of the common SCR controller. The current feedback includes a plurality of resistors that are selectively connected in the feedback circuit according to the number of modules in the power supply so that effective regulation is achieved regardless of the number of modules included. The module packaging is substantially the same with both modules used for high voltage, low current applications and for low voltage, high current applications. The construction of the modules is such as to facilitate interchangeability of many of the parts between the high voltage and low voltage module.
