Voltage generating device for potential therapeutic instrument

Abstract

The invention provides a voltage generating device for a potential therapeutic instrument, and the device comprises a high-voltage generating circuit, an intermediate frequency circuit, a selection switch, and a switching power supply low voltage circuit. The high voltage generating circuit converts a 220V power frequency alternating current into a continuously adjustable stable DC high voltage, and the output is a positive high voltage to the ground. The intermediate frequency circuit converts a 220V power frequency AC power into the intermediate frequency AC high voltage power, and the selection switch outputs the ground high voltage or the intermediate frequency high voltage according to the selection of the circuit. The switching power supply low voltage circuit converts the 220V powerfrequency alternating current into the output stable DC low voltage power, and the switching power supply low voltage circuit converts the power into DC virtual output. The device is capable of realizing the simultaneous output of a high voltage and a low voltage, can realize independent output of the high voltage or low voltage, and can realize simultaneous output of the high voltage and low voltage, and also solves the problems of the mutual interference and high-voltage breakdown between the high voltage and low voltage circuits.
