Power-Combining Class-E Amplifier With Finite Choke [PDF]
IEEE Transactions on Circuits and Systems I: Regular Papers, 2011 A recently introduced power-combining scheme for a Class-E amplifier is, for the first time, experimentally validated in this paper. A small value choke of 2.2 nH was used to substitute for the massive dc-feed inductance required in the classic Class-E circuit.

A Class B switch-mode assisted linear amplifier [PDF]
IEEE Transactions on Power Electronics, 2003 A switch-mode assisted linear amplifier (SMALA) combining a linear (Class B) and a switch-mode (Class D) amplifier is presented. The usual single hysteretic controlled half-bridge current dumping stage is replaced by two parallel buck converter stages ...

In this article, a novel class-E amplifier topology, based on the functioning principle of the stacked converters, is presented. In this amplifier the available output electric power is determined by the addition of the electric power generated by each of the associated devices.

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.

Continuous Class-E Power Amplifier Modes
IEEE Transactions on Circuits and Systems II: Express Briefs, 2012In this brief, a continuum of novel closed-form solutions is derived for class-E power amplifiers (PAs). It is analytically proven that the class-E zero voltage/zero voltage derivative switching conditions can be satisfied for an arbitrarily selected reactive second harmonic switch impedance (Z2S).

Proceedings of 40th Midwest Symposium on Circuits and Systems. Dedicated to the Memory of Professor Mac Van Valkenburg, 2002
Because of its high efficiency (about 96 percent) the class E tuned power amplifier has found applications in DC-to-AC inverters and DC-to-DC converters, and also frequency multipliers. The most basic configuration of a class E amplifier consists of a transistor operating as a switch connected to a load network which, in turn, contains a capacitor ...

Stability of generalized class E amplifiers
Proceedings of the 33rd Midwest Symposium on Circuits and Systems, 2002The circle theorem is used to prove that a generalized class E amplifier is exponentially stable. This suggests driving class E amplifiers with periodic forcing functions that have a period not necessarily equal to the switching period. Some interesting applications of these circuits include high-efficiency AC-AC power conversion. >

Computer control of a Class-E amplifier
International Journal of Electronics, 1988High frequency electrical power supplies used in many industrial applications have to be able to withstand appreciable variations in load impedance. This paper describes the use of a computer to control a Class-E amplifier power supply which is being developed for high frequency induction and dielectric heating applications.

New topology for Class E amplifiers
International Journal of Electronics, 2007A Class E RF amplifier, which can operate into any load conditions without need for other additional circuitry to protect transistors, is introduced. This is provided by the new topology, which is called an inductive clamp. Our topology incorporates inductive clamp circuitry to the basic Class E amplifier circuit and it has all the benefits of Class E ...

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.
