PWM技术主要应用在智能车舵机上,它通过变频调节电压幅值,来改变电压的有效值,从而转换成对车的控制。对智能车的控制起到决定性作用,通过对PWM技术的运用可更好的对车的控制。-PWM technology is mainly applied in intelligent car on the steering gear, it through frequency conversion adjusting voltage amplitude, to change the effective value of voltage, and in the control of the car conversion. To the intelligence of the control car play a decisive role to the PWM, through the use of the car to better control. electrical devices, made practical by modern electronic power switches.
The average value of voltage (and current) fed to the load is controlled by turning the switch between supply and load on and off at a fast pace. The longer the switch is on compared to the off periods, the higher the power supplied to the load is.
