The class Φ2 inverter is a new switched mode type of resonant inverter. This inverter is applicable for very high frequency application. In this paper, it proposes class Φ2 inverter reduced the voltage stress, and improve the dynamic response. The class E resonant inverter is not suitable for high frequency application, because it produce high voltage stress across the switch. The suitable ball...

In this paper, class DE inverter with second order constant K band-pass filter is proposed. In the proposed inverter, the band-pass filter is used instead of the resonant filter in class DE inverter presented at the previous papers. By using band-pass filter, two important results can be gotten. One is the sensitivity of the output voltage to the operating frequency is suppressed by using band-...

A soft-switching inverter topology (the Class Φ) is presented which draws dc source current through a transmission line or a lumped-network approximation of a distributed line. By aligning the inverter switching frequency just below the line’s λ/4-wave resonance, the Class Φ topology enforces oddand even-harmonic content in its drain voltage and input current, respectively. The symmetrizing act...

This paper presents a capacitive power transfer (CPT) system using a Class-E resonant inverter. A Class-E resonant inverter is chosen because of its ability to perform DC-to-AC inversion efficiently while significantly reducing switching losses. The proposed CPT system consists of an efficient Class-E resonant inverter and capacitive coupling formed by two flat rectangular transmitter and recei...

Single-switch inverters such as the conventional class E inverter are often highly load sensitive, and maintain zero-voltage switching over only a narrow range of load resistances. This paper introduces a design methodology that enables rapid synthesis of class E and related single-switch inverters that maintain ZVS operation over a wide range of resistive loads. We treat the design of ClassE i...

In this paper, we present the analytical expression of phase-controlled class-D inverter at any duty ratio. By considering the body-diode of MOSFET effects and harmonic components of resonant current, analytical expression of phase-controlled class-D inverter at any phase shift and any duty ratio can be obtained. The validity of the analytical expression was confirmed by PSpice simulation.
