摘要
A modulation-based fault-tolerant scheme is outlined for an isolated photovoltaic high-frequency-link (HFL) inverter. It comprises a front end dc/pulsating-dc dc/ac converter followed by a unidirectional ac/dc converter followed by an ac/ac converter. The fault-tolerant scheme ensures operation under different types of fault conditions in the front end dc/pulsating-dc dc/ac converter without redundant circuits. Detailed results on the switching scheme as well as experimental validation using a fabricated prototype are presented.
