HIGH STEP-UP CONVERTER The architecture of a high step-up converter introduced from [17] is depicted in Fig. 2, where it contains seven parts including a photovoltaic (PV) module input circuit, a primary-side circuit, a secondary-side circuit, a passive regenerative snubber circuit, a filter circuit, a dc output circuit, and a feedback control mechanism. In this strategy, a coupled inductor with a lower-voltage-rated switch isused for raising the voltage gain whether the switch is turned on or turned off. Moreover, a passive regenerative snubber is utilized for absorbing the energy of stray inductance so that the switch duty cycle can be operated under a wide range, and the related voltage gain is higher than other coupled-inductor-based converters.
