Stacked Class-E Amplifier

IEEE Transactions on Industrial Electronics, 2020
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 ...

Wideband Push-Pull Class E Amplifier for RF Power Delivery

Compel, 2023
This paper presents the design and implementation of a 13.56 MHz push-pull Class E power amplifier with broad-band capabilities. The Class E amplifier utilizes SiC MOSFETs with a custom current-source resonant gate driver. Because the amplifier is a push-

GaN-FET Class-E Amplifier for 60-MHz Radar

European Microwave Conference, 2021
A prototype power amplifier (PA) using GaN FETs is developed for space-based surface-penetrating radar at 60 MHz. LDMOS FETs would typically be used at this frequency, but the need for space-qualified components mandates the use of GaN. A push-pull class-

Power-Combining Class-E Amplifier With Finite Choke

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.

Class E frequency multiplier driving Class E amplifier

Proceedings of Power and Energy Systems in Converging Markets, 2002
In 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, 2012
In 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).

Sensitivity Characteristics of Inverse Class-E Power Amplifier

IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2007
In this paper, an analysis is performed in order to determine the effects that variations in circuit component values, frequency, and duty cycle have on the performance of the newly introduced inverse Class-E amplifier. Analysis of the inverse Class-E amplifier under the generalized condition of arbitrary duty cycle is performed and it is shown that ...

AC-driven class E amplifiers

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 ...
