POWER CIRCUIT FOR LOAD CHANGE OF THE ELECTRIC PRODUCTS

摘要

a micom(10) outputting a power distribution control signal in the condition of the light load by checking whether each load(5) is driven; and a power distributing part(11) lowering the voltage in front stage of the constant-voltage part(4) by varying the distributed resistor of the smoothing part(3) depending on the control signal of the micom(10).
