LCC resonant converter with inductive filter operating in discontinuous current mode (DCM) can achieve zero-current switching (ZCS) for both the power switches and rectifier diodes. Therefore, it is suitable for high-power, low-voltage, high-current power supplies. The DCM LCC resonant converter with inductive filter might operate in different operating modes when input voltage or load changes, which challenges the design. This paper derives a mode boundary map, from which the operating mode of the converter can be easily determined. Based on the mode boundary map, a generalized optimal design procedure is proposed and a set of optimal and normalized converter parameters is determined, which can be easily converted into real parameters according to the converter specification. Three 5 kW prototypes with different converter parameters are fabricated and tested in the lab, and the experimental results show that with the set of optimal parameters, the converter can achieve the highest efficiency over the entire input voltage and load range.Index Terms-Discontinuous current mode (DCM), LCC resonant converter, mode boundary map, optimal design, zero-current switching (ZCS).

“…Series resonant converter (SRC) [6] and parallel resonant converter (PRC) [7] are two basic resonant converters. SRC offers high efficiency at light load, but it has a wide range of switching frequency and its output voltage cannot be regulated at no load [8].…”

“…They are suitable for high-output-voltage low-output-current converters [10][11][12][13]. Parallel resonant converters [14][15][16] have better no-load regulation and are naturally short circuit proof due to the resonant tank inductor. However, high circulating resonant tank current means higher switching losses and the converter is better suited to applications with a relatively narrow input voltage range.…”

“…However, the switches need to withstand high peak resonant current in the later stage of charging and its corresponding complex control methods such as constant on‐time variable frequency control and variable frequency control are the major limitations of this technique [12]. A parallel RC has a higher voltage gain than SRC, which helps to reduce transformer turns ratio and volume [13]. However, there is a large circulating current in the converter, which causes switching conduction loss and reduces converter efficiency.…”
