Two Kilowatt Interleaved MPP Tracker (Buck) Designed and developed an interleaved buck converter for the solar based applications as Input voltage 70-100 V, Output voltage 48 V and current 42 A. The main features of the developed converter are minimum ripple current, minimum losses, and improved duty ratio. Further, the Maximum Power Point Tracking (MPPT) is implemented in the control algorithm in, which is used for solar based applications where the power and current is very high and includes smart algorithm with IoT Integration
