Common-mode inductors mainly play the role of EMI filtering. On the one hand, it is necessary to filter out the interference of external common-mode electromagnetics on the inverter, and on the other hand, it is necessary to prevent the inverter itself from emitting electromagnetic interference to avoid affecting the power grid and the same electromagnetic environment. normal operation of other devices.
Application scenario:
Communication power supply, vehicle power supply, charging pile, medical equipment, 5G base station
