Abstract
An improved power supply circuit which includes a utility power source, a plurality of silicon controlled rectifiers (SCR-SCR), a first battery, a second battery, a first inductor, a second inductor, a first capacitor, a second capacitor and a plurality of power switch elements (Q˜Q). When the utility power source is in a positive half cycle, the SCRand the SCRare turned on; the SCR, the SCR, the SCRand the SCRare turned off; the Qis activated to make the electrical energy directed to the first capacitor through the diode of the Q, and the voltage on the first capacitor is maintained at a constant. Meanwhile, the Qis turned off, the Qis operated to let the current flow through the second inductor to charge the second battery.
