POWER SUPPLY

摘要

PROBLEM TO BE SOLVED: To realize reduction in size for the power supply. SOLUTION: A control winding 15 is provided to a transformer 1B under the condition that this control winding be coupled magnetically with a secondary winding 16 and this control winding 15 be connected with an output current compensating part 20 and an output voltage compensating part 19 to realize control for turning on/off of a switching element 3.
