摘要

随着电子设备精度的发展，对配套高压电源的质量要求不断提高。然而，由于采样的特殊性，隔离式高压电源很难达到高质量。本文提出了基于效率优化的LLC谐振变换器死区时间和分流支路数最优解的设计方法，并对矩阵变压器结构进行了优化，以减小涡流损耗和漏感。最后，制作了功率为20kV/6kW、频率为100kHz的隔离型plc - dct样机，验证了设计方法的合理性和正确性

The Design of isolated high voltage power supply based on LLC-DCT

With the development of the accuracy of electronic equipment, it constantly improves the quality requirement of the matching high-voltage power supply. However, Isolated high-voltage power supply is difficult to achieve high quality due to the particularity of sampling. In this paper, the design method of the optimal solution of dead time and shunt branch number of LLC resonant converer based on efficiency optimization is proposed, and the structure of matrix transformer is optimized to reduce eddy current loss and leakage inductance. Finally, the isolated LLC-DCT prototype is made with the power of 20kV/6kW and the frequency of 100kHz, which verifies the rationality and correctness of the design method
