Class E frequency multiplier driving Class E amplifier
Proceedings of Power and Energy Systems in Converging Markets, 2002In this paper, we propose the Class E frequency multiplier driving Class E amplifier. This circuit is composed of two series connected Class E amplifiers. One of these Class E amplifiers works like a driver circuit. The proposed circuit can reduce the total power dissipation of the driving stage and can work with higher efficiency.

Class-E and inverse class-E switch-mode power amplifiers
Journal of Communications Technology and Electronics, 2012Circuits of class-E and inverse class-E (Einv) switch-mode power amplifiers (PAs) are systemized on the basis of the principle of duality. New PA circuits (four class-Einv PA circuits and one class-E PA circuit) are proposed. The design relationships for values of reactive LC components of PA shaping circuits are given.

Class E/sup 2/ DC/DC converter with second harmonic resonant class E inverter and Class E rectifier
Proceedings of 1994 IEEE Applied Power Electronics Conference and Exposition - ASPEC'94, 2002Class E amplifiers have been used as inverters for highly efficient DC/AC energy conversion. ZVS-Class E inverters need an RF choke and ZCS-types have the turn-on switching loss increasing with operating frequency. Both types have nonzero power loss in the on-state resistance of the active switch. The second harmonic resonant Class E inverter has no RF

Injection-locked class-E oscillator
IEEE Transactions on Circuits and Systems I: Regular Papers, 2006In this paper, approximate and exact analyses of the Class-E oscillator in the injection-locked mode are given. The synchronization band of the oscillation frequency is also studied. Various factors that influence the synchronization band of the injection-locked Class-E oscillator are described.

Resonant DC/DC converter with class-E inverter and class-E rectifier
IEEE Transactions on Industrial Electronics, 1989A new type of high-frequency high-efficiency resonant DC/DC converter is proposed, analyzed, and verified experimentally. It is called a class-E converter because it consists of a class-E inverter and a class-E rectifier. The class-E rectifier acts as an impedance inverter and is compatible with the class-E inverter.

Power oscillator design: class E
Proceedings of IEEE International Symposium on Circuits and Systems - ISCAS '94, 2002An analytic approach to the design of high efficiency tuned power oscillator is presented. By employing large-signal S-parameters, theoretical conditions for optimum operation of the oscillator have been formulated and discussed. Loss due to non-zero switching time, saturation resistance etc. of the transistor employed is accounted for.

20th Annual IEEE Power Electronics Specialists Conference, 2003
Two zero-voltage switching converters with nonresonant and resonant coupling are presented. These are high-order multiple resonant converters in which the circuit modes associated with the converter operations can have different resonant frequencies. By using proper state variable transformations, the authors derive the steady-state responses of these ...
