Sensorless Control for a Switched Reluctance Wind Generator
... where N is the number of samples in a state of commutation, ii is the ith sampled current, and iN is the last current sample. Moreover, z0 = 0, and the term [N (N 2 − 1)]−1 can be obtained from a lookup table (no more than 16 terms), avoiding a mathematical division that requires several instruction ...

Current Model Buck Converter Example LM3495 LM5576
... Susceptibility to noise on the current signal is a very common problem, reducing the ability to process small ontimes (large step-down ratios). As the duty cycle approaches 50% current mode control exhibits sub-harmonic oscillations. A fixed slope ramp signal (slope compensation) is generally added ...

efficiency optimized control of high performance induction motor drive
... Undoubtedly, the induction motor is a widely used electrical motor and a great energy consumer. Three-phase induction motors consume more than 60% of industrial electricity and it takes a lot of effort to improve their efficiency [1]. The vast majority of induction motor drives are used for heating, ...
