A series resonant inductive pickup has a bi-directional solid state switch in series with an inductor and a capacitor is controlled by switch control elements capable of causing the switching elements to repetitively be in either an open or a closed state, so that by varying the closed: open ratio of the switch the time-averaged amount of power picked up by the power pickup can be controlled. Switch is controlled by output of a voltage comparing circuit. A reference voltage source provides a basis for comparison of some fraction of a supply voltage in order to cause the switch to operate. The magnitude of capacitance in relation to the current drawn by the load determines the repetition rate of ON or OFF commands to the switch. If the current drawn by the load tends to zero, the proportion of time during which the switch is open will tend to 100%.
