Ultra high voltage regulator

摘要

An ultra high voltage regulator for converting includes a rectifying circuit, a first transistor, a second transistor, an output capacitor, a first resistor, a second resistor, and a third resistor. The ultra high voltage regulator converts a received alternative current into a direct voltage to an electrical component. The ultra high voltage regulator capable of providing a larger current becomes more compact and thinner in size without cooperating with a mass transformer/high voltage capacitor, which satisfies the request for miniaturization of the electrical components.
