Abstract:
This circuit design is based on the widely used in small power and a variety of
electronic equipment in the field of switching power supply. It is a design of switch
power supply in parallel system, can provide 8V constant voltage. And its power can
reach 16Watt. At the same time, it can according to the requirements of the two
current proportional distribution. It uses a voltage source to control the output voltage,
a current pensating current method, the voltage across the load and the
current through the load control.
Key Word:
switching power supply,Parallel power supply,constant voltage output, fixed ratio
current division
