| Abstract: | A novel adjustable speed system for matrix converter(MC) is proposed which can implement the direct torque control(DTC) of induction motors.A closed-loop control method for the MC based on double line-to-line voltage synthesis has been used in the system.The method is valid to suppress the distortion of output voltages and currents.The new MC-DTC system has double excellence of both advanced technologies.Some simulations and the laboratorial prototype show the effectiveness of the control method and prove t... |
