[原创] TI F2802x系列MCU 36V 32A(1kW)无刷马达驱动方案

TI公司的F2802xPiccolo系列MCU是采用C28x处理器核和集成控制外设的微控制器,哈佛总线架构,工作频率高达60MHz,内部电压稳压器可采用单电源3.3V工作,集成的HRPWM模块可采用双边沿控制(频率调制),模拟比较器具有10位基准电压,主要用于白色家电,开关电源,DC/DC多输出电源,LED照明,PFC,缝纫和纺织机器以及电动自行车.本文介绍了F2802x系列MCU主要特性,功能框图,以及其1kW(36V/32A)无刷马达参考设计框图,电路图和材料清单.

The F2802x Piccolo family of microcontrollers provides the power of the C28x core coupled with highly integrated control peripherals in low pin-count devices. This family is code-compatible with previous C28x-based code, as well as providing a high level of analog integration.

An internal voltage regulator allows for single-rail operation. Enhancements have been made to the HRPWM module to allow for dual-edge control (frequency modulation). Analog comparators with internal 10-bit references have been added and can be routed directly to control the PWM outputs. The ADC converts from 0 to 3.3-V fixed full-scale range and supports ratio-metric VREFHI/VREFLO references. The ADC interface has been optimized for low overhead and latency.
