摘要:
A novel inductor-capacitor-transformer (L-C-T) has been proposed to integrate the passive components into an integrated magnetic component. The phase-shift full-bridge (PSFB) zero-voltage switching (ZVS) converter with a novel L-C-T has high-power density performance, which is used in electromagnetic exploration. The structure of the novel L-C-T is very complicated, and the lumped parameter of the L-C-T is very difficult to determine. Based on the dual method of the magnetic circuit, the electromagnetic energy method and the six-lumped capacitance method, a lumped parameter model suitable for the novel L-C-T is proposed. Moreover, the experiments and finite element analysis (FEA) are used to verify the accuracy of the lumped parameter model, and a 40 kW prototype of the PSFB ZVS converter with a novel L-C-T is designed and tested. © 2019 Institution of Engineering and Technology.
