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.

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 ...

Class E inverters and rectifiers
2008 4th European Conference on Circuits and Systems for Communications, 2008Comparison of class E low dv/dt and low di/dt inverters and rectifiers, which may help in circuit choice. Analytical relationships have been derived for the normalized load resistance and other circuit parameters as functions of the transistor/diode conduction duty factor.

The class-E oscillator with the directed coupler in the feedback is studied. The similar design allows to retune the oscillator with preservation of high efficiency due to a constancy of a directed coupler coupling coefficient in band of readjustable frequencies and absence of the additional selective resonator in the feedback.

It is desirable to obtain high RF power amplifier efficiency in many practical applications. At least one, if not all, of the following requirements is important: low power consumption (especially for battery-operated equipment), low temperature rise of the components, high reliability, small size, and light weight. Although the parasitic energy losses
