漏源电容对双向CLLC谐振变换器升压增益及谐振频率限制的影响

The limitation of the drain-source parasitic capacitance of switches on the boost gain of the bidirectional CLLC resonant converters is revealed in this article. It is found that compared with the ideal CLLC resonant converter without considering drain-source capacitance, a tiny drain-source capacitance would lead to a significant reduction in the voltage boost gain within the below-resonant regio...
