A Simple Explanation of Voltage Spikes and Bearing Current in VFD Fed MotorsMuch has been written about the compatibility of polyphase induction motors with variable frequency drives (VFD's). Both winding stresses and bearing currents have resulted in motor failures under certain operating conditions....
I know the reference voltage can be several different things (1.5v, 2.5v?, some arbitrary voltage that I apply externally to a pin). My question is: What are all the different choices for pre-set and non-preset reference voltages? ...

First, we short-circuit the voltage source. This puts R4 in parallel with R2+R3. We calculate this and get 1k Ohm. This is in series with R1 (also 1k Ohm), so we get an equivalent resistance of 2k Ohms. Then we put these two together and get the following Thevenin equivalent circuit...
You've seen bright red neon signs and other colors of lights, but do you understand how they work? Here's a simple explanation of how neon lights work.
This is a very simple explanation of a relatively complex topic and I would like to point you toward a niceyoutube videoexplanation of similar approaches. Also maybe interesting to say is that for a system like this one there is really no need to run it with the sample times less then ...

Barsukov explained the compass is placed in the middle of a wire coil that is fed with a small alternating voltage. Arefrigerator magnetin the vicinity of the compass aligns its needle. When the fridge magnet is brought closer to the compass, the needle starts to oscillate at a "sweet spot...
Current-mode rectifiers and analysis of diode reverse recovery time influence An explanation of the diode reverse recovery mechanism is provided in a simple circuit. Then a two-diode circuit fed by current is analyzed from the revers... D Kubanek,K Vrba,J Koton 被引量: 2发表: 2009年 Modelin...
