Here are the key reasons it is vital to understand electromagnetic interference in power electronics: Reduced power quality: EMI can cause noise, unwanted voltage spikes, and transients in power systems, reducing overall power quality, efficiency, accuracy, and performance.
Figuring out how to reduce electromagnetic interference in inverters is something that designers must devote considerable attention to. There are various techniques to choose from; EMI filters are one such method, generally used in the input side as well as the output side of inverters to reduce EMI.
In power supplies, the two prominent types of EMI are conducted EMI and radiated EMI. Comprehensive regulations provide limitations to radiated and conducted EMI generated when the power supply is connected to the mains.
Understanding EMI is important as it can affect power electronic systems by reducing power quality, increasing noise levels, interfering with other devices, and reducing efficiency. Common causes of EMI in power electronics include switching transients, common mode currents, and differential mode currents.
Test the Prototype Once the power supply works well inside the specifications, it is worth performing pre-compliance testing of the power supply without an EMI filter, measuring the conducted noise (again, common and differential mode) and checking against simulation results. This will give a first indication of the required filter attenuation.
Comparing the modern power switches used in power supplies with those from older generations, the new switches have significantly reduced switching times, leading to faster and faster rise and fall times for the voltage and current waveforms.
