Switching Low Offset Voltage
Switching Low Offset Voltage

... Designing a 2 pole vs a 1 pole low offset voltage relays are quite different. Generally coil resistance must be as high a value as possible. The higher the coil resistance the lower the power generated across the coil. The lower the coil power the lower the heat it produces. This means we must caref ...

... especially critical when the IGBT is controlled by a source with a series gate resistor. Therefore it is very important to use a gate clamping in such short-circuit cases. Here active clamping (see Figure 20) is the best method today (if a fast diode is used). Active clamping has advantages compared ...

Stepper motor



A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed.Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
