OVERVOLTAGE PROTECTION CIRCUIT

摘要

An overvoltage protection circuit includes a supplying power circuit, a triggering circuit, and a controlling circuit. The supplying power circuit coverts AC power into DC power. The supplying power circuit includes a voltage detective point. The triggering circuit is connected to the voltage detective point. The triggering circuit is triggered when the voltage detective point in a high level voltage. The controlling circuit is connected to the triggering circuit. The controlling circuit includes a power supply point. The controlling circuit cuts off the power supply point when the triggering circuit is triggered.
