| Abstract |
This paper proposes a new high efficiency drive system using an open-winding a.c.
motor and two space vector modulated inverters. This configuration consists of a 3-level inverter with
switching at once every cycle and a 2-level inverter of about 1kHz switching frequency, connected
respectively to the opposite terminals of the open-winding a.c. motor. With the proposed
configuration, good current waveforms, low acoustic noise and high efficiency can be obtained.
Moreover, this space vector modulation system is suitable for the vector control. |
