“…The analysis is based on the assumption that the components of the resonant circuit are ideal. Furthermore, to increase the efficiency of the power supply, the class DE inverter control with 25% duty factor is implemented [43]. The input voltage to the L 1 C 1 L 2 resonant circuit employing a 25% duty factor is shown in Fig.…”

Abstract-This paper describes the analysis and design of an LCL resonant power supply for ozone generation. The main advantage of the proposed topology is the absence of high-voltage transformer; the high voltage gain is achievable by means of doubleresonance phenomena. Furthermore, the bandwidth is wider than the ordinary LC and its phase difference is constant over specific frequency range; as a result, an open-loop operation can be implemented. The complete analysis and design procedure of the power supply is presented. The design procedure is verified by implementing the power supply to drive a dielectric barrier discharge prototype ozone chamber. The hardware results are found to be in close agreement with simulation and thus justify the validity of the design procedures. The proposed circuit is suitable for portable ozone power supply fed by low-voltage source such as battery or photovoltaic module.Index Terms-Dielectric barrier discharge (DBD), full-bridge inverter, high-voltage power supply, LCL resonant circuit, ozone generation.

This paper gives analytical expressions for the output power and the power conversion efficiency of the class-E power amplifier outside the class-E ZVS/ZDS switching conditions. The analytical predictions agreed with the experimental results quantitatively, which indicates the validity of the analytical expressions. Moreover, a design example applying the analytical expressions for the power conversion efficiency is given. By using the analytical expressions, it is possible to design the class-E amplifier, which improves the power conversion efficiency compared with that of the class-E amplifier satisfying the class-E ZVS/ZDS conditions.

“…Several works in the literature related to the Class-DE inverter have focused on the following areas: steady-state analysis with half-bridge switching network at a fixed and any duty ratio [1], [5], [9], [12] and design of inverter with with linear and nonlinear shunt MOSFET capacitances [2], [14], [16], [17]. However, a detailed steady-state analysis of a full-bridge Class-DE inverter at any duty cycle has not been reported.…”

Abstract-This paper presents the following for a full-bridge Class-DE resonant inverter operating at a fixed duty ratio: (a) steady-state analysis using first-harmonic approximation and (b) derivation of closed-form expressions for the currents, voltages, and powers. The conversion from a series-parallel resonant network to a series resonant network is presented. Imposing the zero-voltage and zero-derivative switching conditions, the expression for a shunt capacitance across the MOSFETs in the inverter bridge is derived. The closed-form expressions to calculate the values of the resonant components are presented.A practical design of a Class-DE resonant inverter supplied by a dc input voltage of 230 V, delivering an output power of 920 W, and operating at a switching frequency of 100 kHz is considered and its design methodology is included. Theoretical results are validated by Saber simulations.
