| Abstract | ||||
| 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. | ||||
