Disturbance power simulation in EMI filter design of an Inverter-Driven Air Conditioner

Abstract

In CISPR 14, conducted-EMI emissions and disturbance power are regulated as EMC standards for home electric appliances such as inverter-driven air conditioners. If EMI filter design can not conform to these two standards, longer measurements and redesign are required. Therefore, not only the conducted-EMI emissions but also the disturbance power simulation technique are required. In this paper, we construct the disturbance power simulation technology of the inverter-driven air conditioner, and report the result of comparing the simulation and measured value.
