Document Type and Number:
WIPO Patent Application WO/2007/048270
Kind Code:
A1
Abstract:
A DC power supply circuit is provided, wherein a control circuit controls the ON/OFF
time of a semiconductor switching unit through a SCR drive circuit and a MOS drive
circuit and conducts the semiconductor switching unit when a start section and
a end section of each positive half-wave are lower than a predetermined level,
so that each cut-section obtained from each positive half-wave of the AC source
is used as a charging power. The invention is used to charge a battery or to supply
with a DC power.
