摘要：A programmable DC power supply including a proportionally controlled transistor connected in ries with the load for varying the load current in accordance with the magnitude of a control signal applied to the transistor. A detector coupled across the transistor functions to n high and low voltage thresholds and thereupon lect an incrementally higher or lower voltage for application to the load to assure that the transistor operates continuously in its proportional range, thereby enabling the input signal to maintain control of the load current.
