“…A value for C p is then obtained by solving (6) forÎ in , and substituting into (5). After rearrangement, this gives Since the equivalent-circuit components R Z and C Z are defined entirely in terms of the design parameters f s , R L and C p , they can immediately be found from (9). Subsequently, L s and C s are determined from the required impedance of the equivalent resonant circuit which is necessary to achieve a specific input current, wherê…”

The paper presents five structured design methodologies for third-order LCC voltageoutput resonant converters. The underlying principle of each technique is based on an adaptation of a FMA equivalent circuit that accommodates the nonlinear behaviour of the converter. In contrast to previously published methods, the proposed methodologies explicitly incorporate the effects of the transformer magnetising inductance. Furthermore, a number of the methodologies allow the resonant-tank components to be specified at the design phase, thereby facilitating the use of standard off-the-shelf components. A procedure for sizing the filter capacitor is derived, and the use of error mapping, to identify parameter boundaries and provide the designer with a qualitative feel for the accuracy of a proposed converter design, is explored.

“…1 shows a schematic of an LCLC resonant converter with a capacitive output filter. The absence of an inductor at the output filter causes the input voltage of the transformer to be clamped at the output voltage level that is divided in the transformer turns ratio, n while the power is transferred from the resonant circuit to the output which results in a phase shift between the transformer voltage and current [6]- [8]. Once the output rectifier current reaches zero, the output rectifier diodes turn off and the energy is fed into the resonant circuit.…”

This paper presents an analysis of a 4th order LCLC resonant converter with a capacitive output filter using the state-space approach. The analysis of the converter shows that there are four intervals in a half period. In each interval, the state-space equations are obtained. Due to the soft switching of the converter, an exact equation for the Zero Voltage Switching (ZVS) time and the maximum dead time of the inverter switches are presented. The simulation and experimental results obtained from a 10kv, 370w prototype confirm the validity of the theoretical analysis.

“…Resonant converters is well known for its applications in high power density and high energy efficiency [1][2][3][4][5][6][7][8][9][10][11][12][13] and LLC resonant converters have been studied in plenty literatures [4][5][6][7][8][9][10][11][12]. In literature [4], only the topology of bidirectional resonant circuit is mentioned.…”

Abstract-A novel bidirectional DC-DC converter with LCC resonant net was proposed. The converter was composed of LCC resonant net and traditional bidirectional DC-DC circuit with zero voltage switching (ZVS) operation of the primary side switches and zero current switching (ZCS) operation of the rectifier diodes in forward power transition. This paper analyzed the buck operation mode in the reverse direction. The simulation results illustrates that the proposed topology can realize the power transition in both directions.
