AI Technical Summary
Existing high-frequency transformer design methods in high step-up ratio isolated DC-DC converters suffer from leakage inductance that is not well-matched to the resonant network, making it difficult to meet the overall step-up ratio requirements of the converter. Furthermore, the insulation level requirements are not high, resulting in significant system cost, size, and losses.
By optimizing the winding parameters of the high-frequency transformer to best match its leakage inductance with the resonant inductance, the optimal integration of the transformer and the resonant network is designed, constraints are set, the transformer efficiency is optimized, the overall step-up ratio requirement of the converter is met, and temperature rise verification is performed.
The optimized integration of high-frequency transformers and resonant networks has been achieved, simplifying the system structure, reducing cost, size and losses, improving system performance, and meeting the requirements for high insulation levels.
