Abstract

Electric vehicles and hybrid vehicles have been popularized in recent years. In such a vehicle, an inverter circuit which converts a direct current to an alternating current is mounted. Due to the noise from the inverter, reception quality of AM radio is deteriorated. This paper proposes a novel noise cancellation system composed of a noise sensor and an adaptive filter which is controlled based on PI (Power Inversion) algorithm. Numerical results show that the inverter noises can be reduced by the proposed system.
