Inventor: SUGITO TAKESHI
IPC: H02M3/28
Filed: 2011-02-03
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of recovery of a freewheel diode.SOLUTION: Since a transformer 63 is inserted on a primary side of transformers 41 and 42, even when NMOSs 31, 32, 33, and 34 are turned on, an input voltage Vin is instantaneously applied to the transformer 63 to generate no voltage across primary windings 41a and 42a of the transformers 41 and 42.
