Abstract
Autoranging power supply apparatus may comprise a power output section having a plurality of pairs of output terminals, each of which has a maximum voltage and current rating. A switching network associated with the power output section connects and disconnects the plurality of pairs of output terminals to the external load. A control system connected to the switching network operates the switching network in response to changes in the impedance of the external load to connect and disconnect to the external load selected ones of the plurality of pairs of output terminals of the power output section to compensate for impedance variations in the external load and to prevent from being exceeded the maximum voltage and current ratings for each of the plurality of pairs of output terminals.
