Control of asynchronous motor SVPWM
Abstract The rapid development of today's society, the electric drive is already one of the most important modern electromechanical energy conversion in the form of。 Asynchronous motor behind the development of the relevant technologies mature and produce。 AC motor structure is far less than the DC motor so complicated when their work is not often because of their own lack of a negative impact on life and production, greatly improving the reliability of the motor is operating, the production cost is low alternating-current motor DC motor。 AC motor maintenance and repair is very convenient, but also can be used for many other motors that can not adapt to the natural environment。 It has been widely used in various fields of life and production。 That stable speed control induction motor, it has been a big problem。 Since computer technology since the emergence of humans has been the focus of research and made significant achievements in power electronics technology with social production and life changing requirements of a breakthrough, there are problems on the control of asynchronous motors, the key to solving the problem lies in SVPWM technology 。 Voltage space vector pulse width modulation control is a will to change the asynchronous motor is a rotating magnetic field generated from the motor stator portion starting to form under certain amplitude and frequency of the pulse signal from the stator portion of the inverter output in the corresponding circular stable rotating magnetic field to control a technology motor。 By controlling the voltage applied to the stator on the standard vector to form different voltage space vector pulse width modulation technique used in line with the frequency of the rotating magnetic field corresponding to the rotation of the rotor driven by ideological pulse width modulation (PWM) and sinusoidal pulse width modulation (SPWM) do not have control thought, this is the highlight of SVPWM control technology place。
