Abstrakt

Magnetic chokes are conventionally utilized at the DC or AC side of the Adjustable Speed Drives (ASDs) to suppress low order harmonics of 0–2 kHz. Recently, the frequency range of 9–150 kHz has been noticed as a new disturbing frequency range, interfering with the distribution networks. Due to the novelty of this topic, so far there has not been a thorough investigation on the effect of DC and AC choke configurations on 9–150 kHz emissions, especially for three-phase ASDs. In this paper, the effect of DC and AC choke configurations on common mode current emissions at the frequency range of 9–150 kHz is broadly surveyed in three-phase adjustable speed drives. Subsequently, the comprehensive equivalent models of the system are presented for each configuration of DC and AC chokes. This investigation is based on the comparative analysis of the system's transfer functions according to the presented equivalent model, mathematical calculations and the real system
