ABSTRACT:
A regulated power supply for drawing approximately constant power from an AC supply feeding a load that varies widely. A switching device in series between the AC supply and the load regulates the load current. A control circuit samples the load and controls the on-off state of the switching device in accordance therewith. A second switching device is connected between the AC supply and an auxiliary load and is switched on and off by the control circuit in synchronism as the first switching device is switched off and on, respectively.
