Simulation and hardware implementation of 24 watt multiple output Flyback converter

Abstract

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. 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 Simulation and practical implementation of multiple output Flyback converter with Silicon Carbide (SiC) MOSFET as switching device. The designed Converter is observed to have a good output voltage regulation and higher efficiency for the wide input voltage range.

Magnetising inductance of multiple‐output flyback dc–dc convertor for discontinuous‐conduction mode

“…A short design procedure and component selection for the multiple-output flyback dc-dc convertors have been discussed in [5][6][7][8]. In [5,6], the magnetising inductance was calculated in terms of the total input power or output power and does not take into account the resistance and voltage of the individual output stages. A closedform solution for calculating the magnetising inductance in terms of the load parameters (resistance and voltage) was introduced in [8] for the multiple-output flyback convertor in CCM.…”

“…The multiple‐output flyback dc–dc convertor is a widely used topology for applications such as LED drivers, power supplies for point‐of‐load applications, universal power supplies for laptop chargers, and so on [1–30]. In addition to the several benefits of flyback convertors, the multiple‐output flyback convertors is capable of providing equal or unequal output powers in each stage, isolate each output stage, provide regulated dc output voltages simultaneously, and offer a reduced parts count [1–4].…”

“…The analysis of the single‐output or the conventional flyback dc–dc convertors in both continuous‐conduction mode (CCM) and discontinuous‐conduction mode (DCM) is well documented in the literature [4–33]. A short design procedure and component selection for the multiple‐output flyback dc–dc convertors have been discussed in [5–8]. In [5, 6], the magnetising inductance was calculated in terms of the total input power or output power and does not take into account the resistance and voltage of the individual output stages.…”
