The Design of Two Phase Chopping Regulation Voltage Soft Starter

. As for the complexity of the trigger pulse control method for the generally-used thyristor soft starter, The poverty of the continuity of the stator current, the shortage of the waveform distortion and the higher harmonic content. A type with IGBT to realize AC chopping regulation voltage soft starter has been designed,using the two-phase AC power control to achieve the aim of three-phase AC power control,ensuring the effect and saving the costs. The paper makes use of the MATLAB to analyze of the two phase chopping regulating all control type soft starter start performance with simulation, and designs the soft starter of the hardware circuit and the software programs.
