The new "controlled sources method" to synthesise large-signal circuits of resonant inverters

In this paper, a general method is proposed to obtain the large-signal equivalent circuit of any resonant inverter, independent of its order. The method is illustrated with examples, showing the PSpice implementation of this circuits. Simulation of the large-signal circuits gives all the information (in open and in closed-loop) concerning the static and dynamic performances of the amplitudes and phases of the oscillations, against variations of the switching frequency, duty-cycle and input voltage.
