Common mode voltage impact on wind turbine main shaft bearing
Main shaft bearing is a critical component in the wind turbine rotating system. But the bearing voltage, which is generated by the potential differences between the bearing and the main shaft, often causes the downtime of the main shaft bearing.

Improved dc voltage multiplier [PDF]
Circuit multiplies a dc input voltage in the millivolt range to yield a larger dc output voltage bearing a fixed ratio to the input voltage. The supply voltage need not be precisely regulated, the potentiometer need not be linear, and the gain of servo ...

Time-Domain Sparsity-Based Bearing Fault Diagnosis Methods Using Pulse Signal-to-Noise Ratio [PDF]
A fast and automated technique is crucial for bearing faults diagnosis during operation. To circumvent the intricacies of signal spectrum analysis, a diagnostic method named the pulse signal-to-noise ratio (PSNR) test is proposed by exploiting the time ...
