A Novel High Conversion Ratio Bi-Directional DC-DC Converter

Sarun S S | Anil J Thomas


Abstract: This paper presents, a high-conversion ratio bi-directional dc-dc converter with coupled inductor. In the boost mode, two capacitors are parallel charged and series discharged by the coupled inductor. Thus, high step-up voltage gain can be achieved with an appropriate duty ratio. The voltage stress on the main switch is reduced by a passive clamp circuit. Therefore, the low resistance RDS (ON) of the main switch can be adopted to reduce conduction loss. In the buck mode, two capacitors are series charged and parallel discharged by the coupled inductor. The bi-directional converter can have high step-down gain. Aside from that, all of the switches achieve zero voltage-switching turn-on, and the switching loss can be reduced. Due to two active clamp circuits, the energy of the leakage inductor of the coupled inductor is recycled. The efficiency can be further improved. Simulation of open loop and closed loop control of novel high-conversion-ratio bi-directional dc-dc converter with coupled inductor is done in MATLAB and output is obtained. Hardware implementation of the open loop is being done and the output is obtained.
