Abstract
A resonant tank circuit has an output port configured to be coupled to a load comprising a current-controlled semiconductor device, such as a diode, thyristor, transistor or the like. A voltage generator circuit is configured to intermittently apply voltages to an input port of the resonant tank circuit in successive intervals having a duration equal to or greater than a resonant period of the resonant tank circuit. Such an arrangement may be used, for example, to drive a static switch.
