Abstract: A DC or AC power conversion and regulation system in which DC or rectified AC is applied to a voltage controlled oscillator (VCO). The output of the VCO is applied to a frequency sensitive filter whose frequency response is such that for a fixed input voltage the output voltage is a function of the input frequency. The output of the filter is applied to a transformer whose output may be rectified to provide a regulated DC output. A portion of the rectified DC is sampled and compared with a reference voltage to generate an error signal which is used in a feedback loop to control the operating frequency of the VCO.

Abstract: The invention is a booster-inverter power supply circuit for providing a regulated, inverted DC output. It is made up of a conventional booster-regulator power supply circuit and improved by the addition of an inverter circuit. The conventional booster-regulator circuit includes an unregulated DC input, a booster choke for receiving the DC input, a switch for controlling the booster choke, a voltage to pulsewidth control connected to the switch for controlling the switch, an AC to DC converter for providing a DC to the voltage to pulsewidth control, and an output circuit having an output diode. The circuit is improved by the addition of the inverter circuit having an inverter transformer and a voltage control circuit. The inverter transformer is connected at one end to the switch, the booster choke, and the output diode. The switch controls the voltage on the inverter transformer. The output of the inverter transformer is a regulated AC output fed to the AC to DC converter.
