ABSTRACT:
Measurement of load current when a digitally controlled power supply is in a constant voltage mode and of voltage when it is in a constant current mode is achieved by dropping the current represented by the digital current selection signal in one case and the voltage represented by the digital voltage selection signal in the other case until the power supply would change its mode of operation as indicated by comparators. Actual change of mode is prevented by delaying or interrupting the application of the digital selection signals to their respective regulation circuits.
