Abstract

The high step up dc-dc converter with a quadratic boost converter with voltage multiplier cell (VM) to achieve a high voltage gain in the continuous conduction mode (CCM). To increase higher voltage gain, lower voltage stress on diodes and capacitors and requiring smaller inductors with reduced number of components. Quadratic Boost DC-DC converters are mainly used in applications like HEVs and EVs vehicles. The purpose of boost converter is to charge a low-voltage (12 V) battery during boost mode and to assist the high-voltage 200V battery. In this implementation, closed-loop control in high voltage side is implemented using PI (proportional integral) controller
