摘要： PROBLEM TO BE SOLVED: To reduce load current dependence of charge battery current. SOLUTION: A system includes a charge battery 6 and a direct current power supply 1 connected to a supply regulator 2. The supply regulator adjusts output voltages and restricts output currents so that they become slightly less than the maximum permissible output current of the direct current power supply. Output of the supply regulator provides operation of a portable device. Voltage corresponds to a supply voltage level required for the portable device, and output is further connected to a power input of a battery charger 5 for charging charge batteries, a first terminal of a capacitor, and a first input of a voltage comparator 7. A second terminal of the capacitor is grounded, and the battery charger charges charge batteries with outputs and its operation is controlled by a digital control device 8. In the digital control device, input is connected to output of the voltage comparator and output is connected to the battery charger. The voltage comparator has a reference voltage as a second input and compares the reference voltage with the output voltage of the supply regulator. COPYRIGHT: (C)2010,JPO&INPIT
