| Title | Modelling and Simulation of Electromagnetic Interference from Switching Power Converters |
| Summary | Background Switching power converters are widely used in electronics products. They are much efficient compared to the conventional power supplies, but they generate significant amount of electromagnetic interference (EMI), which leads to disturbances in other devices sharing the same AC power bus. To comply with international standards, a power line filter must be integrated within the power converters to control the EMI. This filter is usually over designed or under designed due to the lack of EMI knowledge. Sometimes, the cost of the product increases significantly due to the cut-and-try approaches adopted to design this filter. Project Scope Firstly, a simple AC-to-DC switching converters will be modelled using SPICE. After that, the EMI can be simulated and a systematic approach to designing a power line filter can be realized. A comprehensive study of different filter configurations will be carried out to design an optimal filter. In this project, the student will learn how to use LT-SPICE tool to simulate a switching power converter and to analyze the results in both frequency-domain and time-domain. Pre-requisite and skills, if any Familiar with LT-SPICE simulation tool. |
