Modeling and analysis of boost active power factor corrector and EMI filter topology for ECM applications
Abstract
Different electronic devices use different switching frequency and frequency band of operation. An electronic device which is connected to an electrical network can interrupt the functional operation of other devices if they are prone to Electromagnetic Interference (EMI). The manufacturer needs to make sure that the device they are producing is not interrupting other devices during the normal and critical operation of the product. Electromagnetic compatibility (EMC) laws enforce electronic devices, medical devices, automotive products, industrial and military devices to function properly in their operating zone without interrupting other devices. Before marketing any product, it is necessary to get the EMC certification. Failure of getting EMC certification is related to loss of money and time. Early prediction of the EMI emission can save money and time. So, it is important for the designer to understand the system behavior and characteristics. This research work investigates early prediction of the conducted EMI emission and noise reduction techniques of the electronically commutated motor (ECM) applications. There are several EMI reduction techniques which are frequently used by the designer. From those available methods, filter implementation is used in this work which is the best solution to reduce EMI. The detail simulation modeling of the EMI measurement test setup is also proposed in this work. Also, different EMI filter topologies and their design parameters are analyzed, and their performance is compared. Boost active power factor corrector (APFC) power supply that is frequently used in a system to improve the performance is also taken into consideration. The simulation results presented here provides valuable information about the design modification and behavior of the system with the change of designable parameters.
