基于单片机死区时间控制方法研究

Research on Dead Time Control Method Based on Single Chip Microcomputer

单片机在嵌入式中应用十分广泛。随着时代的发展,单片机的功能越来越强大。本篇文章是基于stm32系列单片机来产生的死区时间,占空比以及频率可调制的互补输出PWM波。脉冲宽度调制(PWM)是一种模拟的控制方式。利用单片机微处理器的数字输出对模拟电路进行控制的技术。本文利用STM32的高级定时器TIME1进行可调制的PWM波互补输出。

SCM is widely used in embedded applications. With the development of the times, the function of SCM is more and more powerful. This article is based on the stm32 series of single -chip to generate the dead time, duty cycle and frequency adjustable complementary output PWM wave. Pulse width modulation （PWM） is a simulated control method. The single-chip microcomputer digital output is used to control the analog circuit. This article uses the STM32 advanced timer TIME1 to make the modulation PWM wave complementary output.
