FULLY RESONANT POWER SUPPLY

摘要

A power supply produces conditioned and scaled output voltages with low noise. The power supply has various components to produce a plurality of higher output voltages from taps of a multiplier. Components include an internal reference voltage circuit that generates a reference voltage and a sine wave power oscillator circuit and resonant circuit that generates an alternating current and voltage. Components further include a controlled current source circuit connected to the sine wave power oscillator circuit. A control amplifier circuit controls the current level to the controlled current source circuit based on the error between the sampled output and the reference voltage. The resonant transform connected to the sine wave power oscillator circuit generates one or more scaled output voltages on secondary windings. A buffer voltage feedback circuit is connected to an output voltage and the control amplifier circuit for providing a feedback loop to regulate the output voltage.
