Modelling and Design of HF 200 kHz Transformers for Hard- and Soft-Switching Application

摘要

The paper deals with modelling and design of HF 200 kHz (and more) low-power transformers with determinated leakage inductances for both hard- and softswitching applications. The first group features by small value of the leakage inductance contrary to second one demanding that value substantially higher. The further aims of the design are minimized weights and dimensions of the transformers. Results of numerical simulations and experimental verifications of designed transformers operated in converter circuits are given at the end of the paper.
