Title:
回生型スナバ回路
Document Type and Number:
Japanese Patent JP5093950
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize low noise and high conversion efficiency by restraining breakdown of a switching element which is to be caused by a bounce voltage to the switching element, which is due to energy stored in an inductor (primary winding of a regenerative transformer) for preventing an inrush current. SOLUTION: The snubber circuit is constituted to output DC or AC power by intermittently controlling a DC power source Vi supplied to an input side by using an inverter or converter 200 having switching elements Q1-Q4. A primary winding of a transformer T1 having a previously determined turn ratio is connected in series with a part between the DC power source Vi and the switching elements. A series circuit constituted of a secondary winding of the transformer T1, and a diode D5 is connected with the DC power source Vi.
