摘要：
This paper proposes combining an active circuit with a passive EMI (electromagnetic interference) filter, which can suppress the conducted noise of an electric compressor in vehicle air conditioning system. The proposed active filter is characterized by connecting the active circuit in series with the Y-capacitor, ensuring that the volume of the EMI filter is not increased. In an experiment using a vehicle compressor, conducted noise could be suppressed by approximately 12 dB in the frequency range from 150 kHz–6 MHz. © 2024 The Institute of Electrical Engineers of Japan.
