Abstract :
This paper presents a simple power converter topology for driving
a three-phase induction motor with a single-phase AC supply.
Using only two active switches and a triac, the converter can
start the motor with high starting torque and low input current,
and can bring the motor up to full speed using a very
cost-effective, single-phase field-oriented control strategy. The
converter supplies balanced output voltages at rated frequency
with virtually no output distortion and with very high input
power factor. In this paper, the capability contours for
different speed ranges and various operating modes are addressed;
the trade-offs between output torque, torque ripple, input
current distortion, and inverter rating are also explained, and
the proposed control approaches are supported by simulation and
test results.
