基于离散电容谐振DAB的准单级微型逆变器及其控制策略

To satisfy the high-performance power conversion requirements of photovoltaic microinverters, this article proposes a quasi-single-stage discrete capacitor resonant dual active bridge (DAB) converter. The converter introduces a pseudobus and combines the transformer leakage inductance with the discrete capacitors on the DAB secondary side to form a resonant circuit. The resonant operation generate...
