Abstract :
This paper presents analytical expressions for the class-EM power amplifier, taking into account the fundamental-frequency and harmonic components of output currents in the main and auxiliary circuits. By using the proposed expressions, design values for satisfying not only the class-EM ZVS/ZDVS/ZCS/ZDCS conditions of the main circuit, but also the ZVS condition of the auxiliary circuit can be achieved without applying any tuning process. The analytical predictions agreed with experimental and PSpice-simulation results quantitatively, which showed the validity of analytical expressions given in this paper.
