Abstract

A power convertor includes a transformer, a filtering unit, an isolating unit, a starting unit, a rectifier, an accelerating capacitor, a controlling module and an auxiliary capacitor. The filtering unit is electrically connected to the transformer and the isolating unit. The accelerating capacitor is electrically connected to the rectifier and the isolating unit. The starting unit is electrically connected to the rectifier, the isolating unit, the accelerating capacitor, the controlling module and the auxiliary capacitor. The power convertor is shut down when the controlling module enters a latch mode. The isolating unit is configured to prevent an electric power stored in the filtering unit from entering the starting unit when the controlling module leaves the latch mode. The accelerating capacitor obtains a voltage level and rapidly charges to the auxiliary capacitor to make the power convertor restart when the controlling module leaves the latch mode and resets.
