Pulse width modulation has been widely used in ac motor frequency control. Compared with the classical pulse width modulation method, the spatial vector pulse width modulation method has advantages such as high efficiency of dc voltage, simple control, small loss, and easy to digitize scheme. This paper introduces the method of realizing SVPWM using the DSP motor control chip TMS320F2812 of TI company. The control method can produce less harmonic and reduce switching loss in the voltage inverter. - AC motor speed regulation, pulse width modulation technology has had been widely, informs, The space vector pulse width modulation method and The classical PWM methods, a high utilization rate of DC voltage control is simple, The loss of small, easy to realize The advantages of digital designed. In this paper, using TI & # 39; s TMS320F2812 DSP motor control chip to your SVPWM method. The control speed, high precision, The voltage makes can produce fewer harmonics and reduce The switching losses.
