Abstract
A power supply with by-pass function is provided. The power supply comprises an AC-to-DC converter, an input energy-storing capacitor, a ride through circuit, a DC-to-DC converter and an input voltage sensing and logic control circuit. When a voltage value of an input capacitor voltage is in the normal operation range, the ride through circuit outputs an output capacitor voltage according to a first control signal, wherein an output capacitor voltage is equal to the input capacitor voltage. When the voltage value of an input capacitor voltage is in the abnormal operation range, the ride through circuit outputs the output capacitor voltage according to a second control signal, wherein the output capacitor voltage is larger than the input capacitor voltage.
