Abstract
A power supply for a highly inductive load comprises a variable DC source, a unidirectional controlled switching device coupled to the DC source, an inductance in series between the controlled switching device and the load and a capacitance shunting the load. The controlled switching device has a gate coupled to receive a voltage signal functionally related to that across the load so that the controlled switching device will be turned on at the frequency of oscillation of the voltage across the load to provide current pulses to the load.
