| Abstract |
This paper investigates methods to interrupt the
phase currents induced when interior PM (IPM) motor drives
suffer short-circuit or uncontrolled generator mode faults. A
fault-tolerant silicon switch is proposed in which the antiparallel
diode in a reverse-blocking IGBT is replaced in by an
SCR. A reduced parts count fault interrupting topology is also
proposed which consists of delta-connected thyristors inserted
into the center of a wye-connected IPM motor stator. Control of
the proposed reduced parts count fault-tolerant drive is covered
and simulation results are presented to verify operation of the
proposed topology. |
