Abstract

Steady state characteristics of an interior permanent magnet (IPM) motor drive system, which has regenerating circuit of double-layer capacitors, are investigated by simulation. In the system, two voltage boosters are equipped and the double-layer capacitors are arranged in series with battery to reduce the number of capacitors. A strategy to control the power flow of the system and also a strategy of battery current indirect control are indicated. Furthermore, proposed system is investigated for 1.5kW IPM motor drive by simulation and the validity of the strategies is demonstrated. Finally, the relation between the currents of voltage boosters and the ratio of battery voltage to voltage of double-layer capacitors is discussed.
