Boost type direct current output control circuit device controlled by subpower

摘要

A direct current power source includes an electric control unit (ECU101) for converting a portion of input direct current electric energy into alternating polarity electric energy or ripple electric energy. The converted alternating polarity or ripple electric energy is supplied to the primary winding of a transformer, and an alternating polarity or ripple electric energy output by the secondary winding of the transformer is rectified by a full wave rectifier for use as a direct current auxiliary power source. The direct current power source uses voltage accumulation to boost the direct current electric energy, eliminating the need for a full power transformer.
