An electrical load is supplied with energy by a power source, also known as an electrical device. The primary function of a power supply is to convert the source's electrical current into the precise voltage, current, and frequency required to operate a device. In order to lower the leakage inductance through the transformer core winding, the proper transformer design has been implemented. Any power source design should aim to minimize losses while also reducing losses, increasing efficiency, and decreasing size and weight. And also compared to linear power supplies, switched mode power supplies are the more efficient and accuracy at achieving these objectives. With its simple forward design, simplicity in adding numerous outputs, and low cost, forward topology is one of the available smps topologies that is well suited for low to medium power applications. However, the forward topology has a few drawbacks, including poor cross regulation for numerous output topology and high voltage stress across the MOSFET switch. Snubber circuits must therefore be used to reduce the stress across the MOSFET switch, and coupled inductors must be used to accomplish the necessary cross regulation. This undertaking the goal of this work is to design and produce a triple output forward converter with integrated protection circuits that will increase the converter’s dependability. For quicker response, the proposed converter is developed and implemented with primary side voltage mode control using UC2825 PWM IC. The converter runs at a 500 KHz switching frequency. Additionally, coupled inductors are used at the secondary to improve line, load, and cross regulations. Key factors like efficiency, ripple voltages, load, line, and cross regulation at various load circumstances are tested and analyzed for the developed board. The desired 82% efficiency, as intended, is successfully attained.
