Flyback converter

Flyback converter is a dc-dc converter topology derived from buck-boost converter with inductor split up to form a transformer for galvanic isolation between input and output.
The project consists of two parts. First part studies flyback converter application in pre-charging the module capacitors of a Modular Multilevel Converter (MMC). Second part describes the design procedure for a multi-output flyback converter for powering Nixie tube and a microcontroller.
This project was undertaken as a part of B.Tech project (BTP) requirement under the guidance of Prof. Mukul C. Chandorkar at IIT Bombay. The project was completed over the period of two successive semesters.
