BLDC adaptive zero crossing detection compares BEMF voltages from a floating phase of a BLDC motor to a reference voltage, measures a rising time interval during a rising BEMF period when the BEMF voltages are greater than the reference voltage, and a falling time interval during a falling BEMF...
To continue the simulation, you may 1) Try using Adaptive zero-crossing detection algorithm or 2) Disable the zero crossing of the blocks shown in 在时间9.1436072197290515E-006,模仿击中 (1000) 连贯零相交。 连贯零相交将减速模仿或造成模仿垂悬。 要继续模仿,您使用能适应的) 零相交侦查算法可以1次...

A buck converter device with a zero-cross comparator with an adaptive threshold. The buck converter comprises of a control block that controls a first p-channel MOSFET switch, and a second n-channel MOSFET switch. The p-channel MOSFET switch and the n-channel MOSFET switch provide a sense ...
Zero-Crossing Detection no Algorithms The Block LMS adaptive filter algorithm is defined by the following equations. ny(n)e(n)w(k)=kN+i=wT(k−1)u(n)=d(n)−y(n)=w(k−1)+f(u(n),e(n),μ) The weight update function for the Block LMS adaptive filter algorithm is defined...

To overcome this problem (without adding any stray inductance compensation circuit), the device uses a turn-off mechanism based on an adaptive algorithm. This consists in turning off the SR MOSFET with a certain delay after the sensed drain-source voltage has reached zero and adapting ...
