Abstract
A power factor correcting power supply. The power factor correcting power supply includes a controlled current source for providing electrical power of a regulated current and a regulated voltage to a first output terminal, a voltage comparison current controller, and a control circuit responsive to the current at the output terminal, the control circuit coacting with the voltage comparison current controller to cause the controlled current source to increase or decrease the current at the first output terminal.
Claims12
A power factor correcting power supply, comprising:
- a controlled current source for providing electrical power of a regulated current and a regulated voltage to a first output terminal;
- a voltage comparison current controller;
- and
- a control circuit responsive to the current at the output terminal, the control circuit coacting with the voltage comparison current controller to cause the controlled current source to increase or decrease the current at the first output terminal.
A method for operating a power factor correcting power supply, comprising:
- providing, by a controlled current source a voltage and current at a first output terminal;
- determining the current at the first output terminal;
- based on the measured current at the first output terminal, increasing or decreasing the current at the first output terminal without increasing or decreasing the voltage at
- comprising a current sensor measuring current at the first output terminal.
