摘要
采用D触发器及与非门构建“保护型”脉冲宽调制电路和H型双极模式驱动电路,设计出一种适用于高精度伺服系统的直流电动机脉冲宽调制式驱动器。该驱动器具有体积小、成本低、简单适用、安全可靠等优点。已成功应用于某公司的自动控制教学实验仪器上。
This paper introduced the design of protected PWM circuit consisted of D type flip-flops and NAND gates. The design of DC motor PWM driver, which suits high accuracy servo system, is introduced. The driver is of compact design, low cost, simplicity and stability. This driver has been applied successfully to a company＇s product of automatic control education experiment.
