Abstract :
Two-stage matrix converter (TSMC) has many advantages: bidirectional power flow, high quality input/output waveform, simply clamp circuit and compact power circuit. However, as a device without energy storage elements, TSMC has a low immunity to the ac line disturbances, which can degrade its performance and reliability. A novel direct torque control method for induction motor drive system fed by TSMC is proposed. Theory analysis and simulation results show that it can improve the drive system performance and has strong robustness for input voltage.
