ABSTRACT:
An electronic power amplifier includes a plurality of cells, each cell comprising a DC input port for accepting a DC input power from a voltage source VG, an AC input port for accepting an AC signal S1at a frequency FSand having a first magnitude M1, a switching mechanism operatively coupled to the DC input port and to the AC input port for converting the DC input power to an AC output power at the frequency FSand having a second magnitude M2greater than the first magnitude M1, and an output port capable of applying the AC output power to a load impedance. The plurality of cells includes at least a first cell having a first DC input port and a second cell having a second DC input port. The first and second DC input ports are connected in series for application to the voltage source VG.
