Abstract
A method to provide high resolution power control in SCR based power supplies utilizing dithering designed to introduce perturbations in the control signal to the power supply controller or firing circuit+, and to thereby control the output of the power supply with increased resolution.
Claims5
A method for controlling an SCR based power supply, comprising:
- providing an SCR based power supply including at least a user interface, said user interface configured for allowing a user to enter one or more of a desired power supply power value, a power supply voltage value or a power supply current value, a controller, an SCR firing circuit and a dither signal generator;
- said SCR based power supply receiving, from the user interface, said one of said desired power supply output voltage value, said power supply current output value, or said power supply power output value;
- providing, by said SCR based power supply said desired one of a power supply output voltage value, power supply output current value or power supply power output value to a dither generator;
- and
- responsive to said received one of a power supply output voltage value, power supply output current value or power supply power output value, said dither generator configured to provide a dither control signal.
