In this paper, a single- phase to three- phase converter is proposed. to provide
variable output voltage and frequency. The proposed topology employs only six
IGBT switches, which form the front-end rectifier and the output inverter for the
one step conversion from single-phasc supply to output three-phase supply. The
front-end rectifier permits bidirectional power flow and provides excellent
regulation against fluctuations in source voltage. Moreover, it incorporates active
input c~u-rent shaping feature. An easy method to implement control strategy is
proposed. This control strategy ensures nearly unity input power factor with
sinusoidal input current over thc operating range. Based on vector control
technique, the proposed converter is used for speed control of three-phase
induction motor. A low cost of motor drive can be achieved using the proposed
technique. Simulation and experimental results are carried out to analysis and
explore the characteristics of the low cost drive system.
