摘要：

A novel multiresonant dc-dc converter is presented in this article, which owns a wide input voltage range and better voltage gain characteristics. Due to the addition of an antiresonant tank with a notch filter function, the converter introduces third harmonics in the power transmission, which can reduce the circulating energy in the resonant tank and reduce the loss of rectifier diode, thus improving the efficiency. The CL-LLC converter can realize soft switching in the full-load range. This article introduces the operating principle of the converter and the method of the parameters design. Finally, a 350-500 V input and 24 V/400-W prototype is designed to verify the correctness of the theory.
