ABSTRACT:
A highly efficient, tuned, switching power amplifier has components in a circuit configuration which minimizes switching losses and stored energy within the circuit. The circuit includes a pair of switches operating at the carrier frequency at substantially 50% duty. The switches are coupled through a transformer to a load, with the circuit being tuned, taking the particular load into account, so as to minimize the power loss in the switches by ensuring that immediately prior to, and during each, transition of each switch from its non-conducting (off) state to its conducting (on) state, both the voltage across the switch and the first derivative with respect to time of the voltage across the switch are substantially zero.
