摘要

Three-phase motors are used in a variety of applications, such as industrial machinery, water pumping stations, and electric vehicles and transportation systems. They may be easily operated from a single-phase power source by using a suitable power converter to drive three phase motors from single-phase ac source. This paper proposes a single-phase to three-phase (SPTTP) converter with boosting capability of three-phase output voltages. The proposed configuration reduces the number of switches which is only six semiconductors and increasing the three-phase output voltages of single-phase ac source. Moreover, it improves the input and output currents profile of total harmonic distortion (THD) without using another switches in rectifier side. The fewer semiconductor switches and passive components leads to lower power losses and improved efficiency. The toggling control strategy employs a straightforward logic control circuit that is dependent on Sinusoidal Pulse Width Modulation (SPWM) technique. The modulation technique is simple approach rather than Space Vector Pulse Width Modulation (SVPWM) which used in the compared topologies. The architecture’s robustness and effectiveness are verified through the use of MATLAB/SIMULINK. The simulation analysis is verified by setting up and testing a prototype for this topology in the laboratory using a dSPACE-1104. Finally, the desired circuit is approved by the simulation and experimental results, which are examined by the good similarity under a variety of conditions.
