High step-up isolated efficient single switch DC-DC converter for renewable energy source

(in lingua inglese)

This isolated high boost converter with switched capacitor and magnetizing inductors is used to get the high voltage gain. The transformer isolation can be accomplished and it provides better significant influence on efficiency of whole energy condition system. An application of fast recovery diodes eliminates the reverse recovery problems. Thus allows quick diode turn-off without significant power losses. The leakage inductor of the clamp circuit achieves ZCS condition. High boost voltage operation can reduce stress on active switch.
