Application background
Pulse modulation technology by certain rules to control the on-off of the switching element, to obtain a set of constant amplitude and width of the rectangular pulse waveform, is used to approximate sinusoidal voltage waveform. Pulse width modulation technology in Inverter Application in modern power electronics technology and the development of modern speed control system to play a great role in promoting. In recent years, the high frequency SPWM (sinusoidal pulse modulation) technology has been widely used in the motor control system due to the continuous emergence of the field control devices.Key Technology
SPWM (Sinusoidal PWM) method is a relatively mature, the current use of a wide range of PWM. One of the important conclusions of the theory of sampling control is that the impulse is equal and the narrow pulse with different shapes and different shapes are basically the same as that in the process of inertia.
