  在这一章中，先简述了无刷直流电机的转子位置器检测方法；然后论述了反电动势过零检测原理和算法以及该算法的软件实现、软件滤波和相移修正、换相点的软件实现；最后对软件开环换相起动策略作了详细论述。
• High - frequency link power converters are receiving increasing attention . when the input frequency of ac - ac converter is quite high , such as 20khz or above , in order to make sure the converter switching action is restricted to the zero crossing point of the link voltage , the switching cycle becomes discrete pulse spectrums , however , the conventional pwm converters are ruled out because they would fail either to the efficiency or the low - distortion criteria
  当交-交变频器的输入频率非常高，通常为20khz时，为了在零电压条件下实现逆变器开关管的通断，变换器的开关时刻必须选择在高频交流电压脉冲为零时，这意味着变换器开关时刻在时间轴上成为不连续的点，而常规的硬开关pwm变换器是将开关时刻选择在任意时刻。
• The chip jk3ce that is one of micro - controllers in motorola 68hc08 family is used as control unit in this system . the zero crossing point of the back emf can be obtained by comparing the terminal voltage with the virtual neutral point , then using the software of the system can figure out the commutation period . the electronic commutation replaces the mechanical commutation in this way
  本系统采用的控制芯片为motorola系列单片机中的jk3ce ，反电势过零点可以通过比较电机端电压和虚拟中点电压来得到，将过零点信号送往单片机捕捉端口后由系统软件来确定换相时刻，这样就可以由电子换向装置替代机械换相装置，有利于提高系统运行的可靠性，并降低了系统维护的费用。
