This paper presents a novel design procedure for Class E amplifiers without using waveform equations. By the proposed design procedure, Class E amplifiers can be designed regardless of the Q factor of resonant circuit, existence of the switch on resistor, and so on. The proposed design procedure requires only circuit equations and design specifications. All design procedures reported until now require deriving waveform equations which requires a lot of work. The benefits of the proposed design procedure is that it is to deriving waveform equations is no longer necessary. When the circuit equations are obtained, the other procedures for computation of design values are carried out with aid of computer. Therefore, we can design Class E amplifier more easily than the conventional design procedure. The authors design Class E amplifiers by using the proposed design procedures and carry out the circuit experiments, and find that the experimental results agree with calculation results, and show the validity of the proposed design procedure.
