　　2015年10月8日，致力于亚太地区市场的领先半导体元器件分销商—大联大控股宣布，其旗下品佳推出基于Infineon的XMC1302系列微控制器的三相霍尔传感器直流无刷风机180度控制解决方案。

　　在当今节能减排的要求下，直流无刷电机作为一种新的电机类型，具有效率高、控制简单等优点，正逐步取代原先效率较低的交流异步电机。但传统的直流无刷电机由于采用梯形波控制，存在着换向噪声较大的缺点。但如果换成正弦波控制，则可以很好的解决噪声问题。

　　大联大品佳此次推出的XMC1302直流无刷风机正弦波控制系统主要由霍尔信号采样、转速计算、转速PI调节和PWM生成等部分构成。由转速调节电位器或上位机通过串口设定转速给定值;根据直流无刷风机的霍尔信号进行转子位置估算和转速计算，得到的实际转速值和给定转速一起进入转速PI调节器，其输出为PWM调制幅值;通过以上PWM幅值和转子位置信息可以计算得到驱动电机的三相PWM信号，通过逆变电路驱动直流无刷风机运转。本方案采用的调制策略为开关损耗最小SPWM。

　　Target Applications:

　　Motor Control (eBike, power tool):

　　In general XMC1000 microcontrollers can be found controlling, flying or moving around on board many different types of drones and eBikes around the world.

　　Some functionalities that makes XMC1300 suited to motor control application:

　　Easy 3-phase inverter implementation with a single CCU8 PWM unit, offering shadow register transfer, external input for fault control, binary and floating pre-scaler, 16-bit to 64-bit width

　　POSIF interface to directly connect hall sensors and incremental encoder.

　　12-bit ADC with on-chip adjustable gain of x1, x3, x6 or x12

　　Smart Lighting:

　　XMC™ microcontrollers help bring this new dimension into traditional LED lighting systems. With their Brightness and Color Control Unit (BCCU), XMC1300 series products offer an industry-unique module for automatically controlling the dimming level and color of multi-channel LED lamps and can also add DALI or DMX communication capability, facilitating advanced single-chip smart lighting solutions.

　　Some Key features for smart lighting applications:

　　Automatic brightness control (using high-frequency pulse density modulation) based on the ∑∆ principle enables completely flicker-free dimming through 9 output channels

　　Automatic exponential dimming and linear intensity changes make brightness or color changes appear smooth and natural to the human eye

　　Switched mode power supplies:

　　Power supply designs are subject to ever-increasing requirements. Some of them are fueled by customer demands or industry association guidelines (such as higher power density, communication, modularity or the 80 Plus Titanium efficiency standard).

　　Some functionalities that makes XMC1300 suited to motor control application:

　　Rich connectivity: 2x Can nodes, 4-channel serial COM unit (configurable to SPI, I²c, I²S, UART),USB FS.

　　UP to 4X 12-bit ADC with a sample time of 70 ns ensure fast reaction times and tighter control loops.

　　Analog comparators with only 3 mV input offset voltage and a propagation delay of 30 ns.
