A Conventional Double Boost Converter with Voltage Multiplier Cell for Photovoltaic (PV) Applications
Isah H., Sagagi Y. M. and Tampul H. M.

A double boost converter integrated with voltage multiplier cell for photovoltaic (PV) application and other renewables that requires DC-DC step-up control is presented in this work. The new topology was constructed using two conventional boost converters incorporated with voltage multiplier cell and it adopts only one active power switch. The merits of the converter are higher voltage transfer ratio can be obtained at the expense of low duty-cycle and voltage stress across the semiconductor devices is reduced to minimum. The operating principle and steady-state analysis of all the active components of the reported converter were analyzed and presented in details. The simulation and theoretical analysis was done using 10 V DC input and 115 V DC output. Laboratory prototype of the proposed circuit was developed and tested with PV panel.
