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...
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 ...
The difference lies in the treatment of queries for which an algorithm is not applicable. While it is possible to assign such queries an AP of zero, doing so is harsh because the algorithm can correctly inform the user that it is not applicable. From an engineer’s perspective, being given...
Zero-Crossing Detection no Algorithms expand all Frequency-domain adaptive filtering consists of three steps - filtering, error estimation, and tap-weight adaptation. This algorithm implements FIR filtering in the frequency domain using the overlap-save or overlap-add method. For more implementation deta...
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 ...

An adaptive moving average automatically adjusts itself to suit the prevailing market condition. It uses a continuously variable exponential moving average smoothing constant that increases as the price trend slope approaches the 90 degrees angle and decreases as the price trend slope nears zero. In ...
(steps 3 through 5 in the algorithm shown in [ 27 ]). other association mapping methods have been shown to be more accurate than stratified regression. these include the fixed effects model methods and mixed model methods that we consider in our study. as suggested by [ 17 ], the true ...
The algorithm changes the time between the zero current detection and the MOSFET turn-off of the low-side MOSFET and cycle-by-cycle copies the total on-time to the high-side MOSFET. The time shift applied is directly con...
the ADC range control component, as further described herein. In a another non-limiting aspect, removing the at least one glitch can comprise removing the at least one glitch according to the glitch removal algorithm comprising at least one of zero-crossing detection, filtering, or signal ...
