In conjunction with above-mentioned comprehensive, this circuit working state is as follows:
State one: when the DC adjuster is having under input voltage (DC5.5V-14V) state, in the situation that does not insert any load, the DC adjuster will enter the low-power consumption standby state, enter mode of operation at any time;
State two: when the DC adjuster is having under input voltage (DC5.5V-14V) state, the situation that inserts load is being arranged, because the ohm property of load, to reduce output voltage, this moment voltage sample circuit with the voltage sampling of output to the PWM modulation circuit, the PWM modulation circuit will be regulated the electronic switch conducting pulse duration in the DC-DC circuit, the reduction of tasting output voltage with benefit; When being sampled to load current, current sampling circuit exceeds design during designated value, to export a signal and give the PWM modulation circuit, the PWM modulation circuit will be regulated the electronic switch conducting pulse duration in the DC-DC circuit, to reduce output current value, with Current Control in design load; Entire circuit just can play the purpose of permanent power output like this.
During use, the ac plug of the ac terminal (22) of selection and AC socket identical standard, AC-input voltage: supply power voltage AC100-240v, minimum voltage 90v, ceiling voltage 264v; Input supply frequency: 47-63Hz; Load 700mA (maximum input current can reach 750mA) input current is smaller or equal to 100mA.
After charged, the chargeable back-up cell device can take off from charger, packs into to take satchel (25), carries.Allow the output interface (41) of charging reserve battery device of the present invention and the DC-DC plug (241) of DC-DC output line plug, the adapter that selection and used digital equipment charging plug are complementary and the plug (244) of the DC-DC output line other end plug, and the end that adapter and this digital equipment charging plug are complementary just can plug with this digital equipment charging plug.During use, but the charge and discharge situation of Real Time Observation electric weight and other relevant demonstration.
