Abstract: This paper proposes the implementation of step-up converter implemented in the PV solar system, which is considered as the one of the fastest growing renewable energy sources. Here step-up converter is considered which can be designed to extend step-up gain and the switched capacitors can offer extra voltage conversion ratio thereby making it more beneficial than that of the existing converters. A conventional interleaved boost converter obtains high step-up gain without operating at extremeduty ratio. The configuration of the proposed converter not only reduces the current stress but also controls the input current ripple which decreases the conduction losses and extends the durability of the source. In addition, due to the lossless passive clamp performance, leakage energy is recycled at the output terminal. Hence, large voltage spikes across the main switches areelevated and the efficiency is improved. Here the low voltage stress encourages the adoption of lowvoltage-rated MOSFETs for the reduction of both conduction lossesand cost. This proves that the proposed system is also cost effective and efficient. For the case here the system is considered with themotor load.
