ABSTRACT:
A high voltage power supply method and apparatus is disclosed. An example power supply circuit includes a rectifier circuit coupled to receive an AC input voltage. A switchmode power converter circuit is coupled to the rectifier circuit to receive a rectified input voltage to generate a regulated output voltage. A switch is coupled between the rectifier circuit and the switchmode power converter circuit. A sense circuit is coupled to detect the AC input voltage. The sense circuit is coupled to turn off the switch when an absolute value of the AC input voltage exceeds a first threshold value. The sense circuit is coupled to turn on the switch when the absolute value of the AC input voltage is below a second threshold value.
