Summary:
Electric vehicles and hybrid vehicles have been popularized in recent years. In such a vehicle, a PCU (Power Control Unit) which controls the power of electric motors is mounted. An inverter circuit which converts a direct current stored in the battery into an alternating current is included in the PCU. Due to the noise from the inverter, communication quality utilized on the vehicles is deteriorated. This paper, proposes a novel noise reduction system composed of a noise sensor and an adaptive filter which is controlled based on PI(Power Inversion) algorithm[1]. Numerical results show the noise reduction effects by the proposed system.
