A New High Step-Up DC-DC Converter Based on Voltage Multiplier Cell and Coupled Inductor

In this paper, a new topology of high step-up DC-DC converter with a combination of voltage multiplier and coupled inductor is presented. This topology is suitable for more electric aircrafts in the aviation industry. In the proposed topology, high voltage gain can be achieved by low duty cycle. Hence, the low voltage stress is made among the active components. As a result, conduction loss is reduced and the converter works with higher efficiency. The proposed topology has an active switch that leads to simple control operation. Moreover, the continuous input current is another advantage of the proposed topology. Simulation results confirm steady-state operation and mathematical equations of the proposed topology. Simulation is done by plecs software under ۲۰۰w output power and ۱۱.۲۵ output voltage gain.
