“…The topologies of Figure 22(e) -(k) are less popular. The topology of Figure 22(l) is CLL, which has been much publicized in the literature as well [82]- [86] and is similar to the LLC presented in Figure 22(a). Both have two inductors, one in series and another in parallel, and one capacitor.…”

“…In Fig. 17f, to get the desired output voltage at 25% full load, adjusted frequency is [17,18,20]. At onetenth full load, the frequency with D = 0.5 was crossing more than For observing the performance during dynamical operation, the output voltage to the step change of loads from light load to full load is experimentally evaluated.…”

“…To overcome these drawbacks in the aforementioned methods, a hybrid control strategy is introduced in which frequency or duty cycle is adapted independently to control the output voltage. However, actions of frequency and duty cycle are one after the other but not at the same time which leads to wider excursion and resolution of digital signal processor (DSP) [10,[17][18][19]. Moreover, the asymmetrical duty cycle may lead to the core saturation, and regulation of the voltage at very light load condition is difficult, also the switching frequency excursions increase and degrade the efficiency of the converter [20].…”

A modular structured 12-kW resonant converter with effective zero voltage switching (ZVS) is proposed to integrate renewable energy lower voltage source to the microgrid. In this study, duty cycle control is adopted until ZVS fails and thereafter, sequential and parallel adjustment of duty cycle and the switching frequency is proposed for effective output voltage regulation. The proposed control logic ensures ZVS and output voltage regulation over wide load range even at very light loads compared to conventional control methods. Further, it maintains very high system efficiency with narrow range of frequency operation. Hence, it is easy to implement using a conventional digital controller. To minimise ripple current, each of the four converters is provided with 90° phase delayed gate pulses under the proposed control scheme. This study presents an optimal design of the tank circuit elements assimilating high permeable powder cores to reduce magnetic loss and operation with IGBT switches at an optimum point to reduce conduction loss for enhanced system efficiency. A 12-kW, 400-1600 V developed prototype is tested and experimental results are discussed.

“…The LCC resonant converters resemble the characteristics of the PRC at light load conditions depicting the reduction in efficiency. The capacitorinductor-inductor (CLL) resonant converters [15][16][17][18][19][20][21] overcome the downsides of SRC, PRC, and LCC resonant converters by maintaining high efficiency at light load conditions and provide good voltage regulation.…”

Normal phase-shift and modified pulse-width modulation gating schemes are proposed for a full bridge highfrequency capacitor-inductor-inductor (CLL) resonant DC-DC converter, and its performance is analysed in this study. Detailed modelling and the steady-state analysis of the converter are performed by using the fundamental harmonic approximation approach. Various modes of the converter operation with both the gating schemes are described and examined in detail. Zerovoltage switching of all the main switches is achieved by designing the resonant converter to operate in the above resonance mode. The optimum design of the converter is illustrated with the help of a flowchart and design curves. PSIM simulation is carried out and the experimental prototype is built to substantiate theoretical performance predictions. The simulation and experimental results are presented and compared.
