Low profile offline switch mode power supply
Exhibitor: Weng Hoe Wong Joel Supervisor: Richard Cocks – The aim of this project is to produce a low cost Switch Mode Power Supply (SMPS) to power low energy embedded products. The module should be able to handle a wide range of input voltages and produce a steady output at 3 or 5 volts. In addition, the unit must produce power from 500mW to 2.5W with a maximum component height of 12.5mm.
With the completion of this project, I hope that the switch mode power supply can provide highly efficient power conversion in several countries. As the module is design to handle a universal input voltage range, this goal can be achieve.
The objectives of this project have been met as the final product has fulfilled all the specified parameters. However, if I were given a chance to re-design the power supply, I would use a masked PCB so that I can place the components closer to each other. That way, the size of the power supply will be further reduce. In addition, I would like to have multiple voltage outputs (by introducing more secondary windings) to improve the product’s functionality.
