This paper deals with common‐mode (CM) electromagnetic interference (EMI) in an inverter‐fed motor drive system. A simplified CM equivalent circuit including π‐type equivalent circuit for the motor winding is proposed by using the waveform of the common‐mode current flowing in the ground conductor. Moreover, a parameter identification method applying the computer‐aided software modeFRONTIER is proposed...
The disturbance voltage of air conditioners may be degraded, depending on the combination of the outdoor and indoor units. This paper describes a technique to simulate the disturbance voltage of an air conditioner and examines the propagation path of conductive noise when two or more indoor units are connected to the outdoor unit.
This paper presents a discussion on common-mode (CM) electromagnetic interference (EMI) in an inverter-fed motor drive system, and proposes a non-linear CM equivalent circuit. The effectiveness and necessity of the non-linear element introduction are confirmed.
