摘 要:

PROBLEM TO BE SOLVED: To provide a

step-up-and-down chopper DC-DC

converter that can output power quickly

on starting with simple

control.;SOLUTION: A voltage of stored

electricity of an output smoothing

capacitor 55 is increased gradually by the

simultaneous on-off control of transistors

T1, Q2 of a step-up-and-down chopper

circuit 51 until the output voltage Vout of

the chopper circuit 51 becomes smaller

by a predetermined value ΔV

than a low threshold value V1 for starting

a through-mode. When the output voltage

Vout reaches the low threshold value V1

for starting the through-mode, the

chopper circuit is shifted immediately to

one of the through-mode, a step-up

mode, and a step-down

mode.;COPYRIGHT:
