摘要
A power supply is provided. The power supply in one form includes a rectifier circuit, a capacitor and an RC circuit. The rectifier circuit is configured to receive a three phase AC signal. The rectifier circuit has a positive output connected to a positive node and a negative output connected to a negative node. The capacitor is connected in parallel with the rectifier circuit between the positive node and the negative node. The RC circuit includes a resistor and capacitor connected in electrical series connection where the resistor and capacitor are connected between the positive node and the negative node in parallel with the first capacitor and the rectifier circuit.
