DC-DC converters are mainly used to provide required output voltage by suitably controlling the pulse width modulated (PWM) signal given to the gate of the fast-acting power electronics switches. The flyback converter is one such popular isolated DC-DC converter topology used to obtain regulated output voltage in low power applications. They are used as power supply systems in space technology and in many other industrial power electronics systems, where having constant voltage is very much essential. This paper presents the practical implementation of multiple output Flyback converter with MOSFET as a switching device. The designed converter is observed to have a good output voltage regulation and higher efficiency for the wide input voltage range.
