ABSTRACT:
A power supply with adjustable outputted voltage includes an AC power input processing circuit and a DC power input processing circuit. The AC power input processing circuit has at least one voltage adjuster that is electrically connected with the DC power input processing circuit for adjusting the outputted voltage. The DC power input processing circuit includes a current sensor, a DC/DC converter, a ripple filter, and a DC/DC self-drive switch. When an extremely large inputted current is detected by the current sensor and the DC/DC converter stops actions, the DC/DC self-drive switch is turned off to protect the circuit.
