Abstract
In this paper, a high step – up converter which is suitable for renewable energy
system connected to grid is proposed. Conventional step – up converters required for grid
application cannot achieve high step – up conversion with high efficiency because of the
resistances of elements or leakage inductance. The proposed converter is a conventional
interleaved boost converter with voltage multiplier module which not only reduces the
current stress but also constrains the input current ripple which decreases the conduction
losses and lengthens the lifetime of the input sources.
