AI summary

An adjustable zero voltage to high voltage power supply electrically receives a voltage source and electronically receives a control signal. The adjustable zero voltage to high voltage power supply includes a first modulator generator, which provides an adjustable voltage signal equivalent to the operating range of the first modulator generator. A second modulator generator receives the adjustable voltage signal and produces a modulated signal. An adjustable pulse width modulator transmits a clock signal to the second modulator generator to control a frequency of the adjustable voltage signal and cause the second modulator generator to produce a modulated signal. A plurality of integrated circuits is configured to receive a control signal and feedback a signal to the first modulator generator and the adjustable pulse width modulator to change from a fixed frequency to a variable increasing frequency.
