Patent Images
1. In the power supply having a pair of control circuits for providing voltage-supplying and current-supplying operating modes, a power supply output monitoring method, comprising the steps of:
- (a) providing digital numbers representative of power supply output voltage and current limit values;
(b) producing in one of said pair of control circuits one of the voltage and current limit values in accordance with said digital numbers, wherein the control circuit producing the limit value is balanced and the other control circuit is unbalanced;
(c) detecting which one of said pair of control circuits is balanced; and
(d) providing a digital number to a display device in accordance with the detected balance control circuit, wherein the displayed digital number is proportional to the particular limit value being produced.
