随着电力电子技术、微处理器技术以及新的电机控制技术的发展，交流调速性能日益提高。变频调速技术的出现使交流调速系统有取代直流调速系统的趋势。但是国民经济的快速发展要求交流变频调速系统具有更高的调速精度、更大的调速范围和更快的响应速度，一般的通用变频器已经不能满足工业应用的需求，而交流电机矢量控制调速系 ...

In higher power applications to utilize the full line power and reduce line currentharmonics

该论文讨论如何采用一种串行无逆的Berlekamp-Massey(BM)算法,设计应用于DVB系统中的RS(204,188)信道编码/解码电路,并通过FPGA的验证.RS解码器的设计采用无逆BM算法,并利用串行方式来实现,不仅避免了求逆运算,而且只需用3个有限域乘法器就可以实现,大大的降低了硬件实现的复杂度,并且因为在硬件实现上,采用了3级流水线(pipe- ...

General Description The LM621 is a bipolar IC designed for commutation of brushless DC motors. The part is compatible with both three- and four-phase motors. It can directly drive the power switching devices used to drive the motor. The LM621 provides an adjustable dead-time circuit to eliminate ``s ...
