以PWM气动调压阀为例说明了如何合理地选择载波频率,既保证了系统的输出纹波达到允许范围之内,又尽量使得载波频率为最低,从而最大限度地延长了高速开发阀的使用寿命.
The PWM pneumatic pressure regulator is taken as an example to show how to select the carrier frequency reasonably. It not only ensures that the output ripple of the system is within the allowable range but also minimizes the carrier frequency so as to maximize the use of the high-speed development valve life.
