Title: Switching power source
Inventor: MEGURO TAKESHI
IPC: H02M3/155
Filed: 1993-11-01
Abstract: PURPOSE:To stabilize the operation of a switching element and reduce loss by obtaining a power supply for a drive circuit to drive the switching element from an output voltage boosted. CONSTITUTION:An input voltage Vi is boosted by the switching performed by a switching element Q1, and an output voltage Vo higher than the input voltage is output to a load Ro. Therefore, a power supply voltage of a drive circuit 1 increases as the output voltage Vo rises, and the drive circuit 1 drives the switching element Q1 with a higher drive voltage. That is, the switching element Q1 is driven by a low input voltage Vi instantaneously immediately after the start of operation but thereafter is driven by a high output boosted voltage Vo. By doing this, the drive circuit 1 fully drives the switching element Q1 and guarantees the stable operation, thereby reducing the loss of the switching element Q1.
