Crowbar resistors are three phase resistance banks which are connected to the rotor windings of the DFIG (Doubly-Feed Induction Generator) such as wind power generator. They are used to prevent damage to the inverter circuits attached to rotor side when a fault occurs in the grid. DFIG power converter, which has a restricted over-current limit, needs special attention during faults in the grid. If the rotor current or DC link voltage reaches the threshold value, crowbar resistors disconnect the converter in order to prevent the generator turning into a squirrel cage induction machine. By crowbar resistors, the DFIG could stay connected to the grid and continue its operation.

FEMTO Messtechnik GmbH
In order to achieve an extremely low noise performance very high gains were chosen, while nevertheless minimizing the associated bandwidth reduction.Thus, as a result of our sophisticated development efforts we can offer a professional "High-End" Current Amplifier line. The noise performance of our products surpasses by far that of conventionally designed OpAmp current-to-voltage converters at the corresponding bandwidth.

Fluke Calibration
The new 50 MHz wideband option for the 5730A High-Performance Multifunction Calibrator provides expanded wideband capabilities to self-maintaining laboratories by providing a method to calibrate the 50 MHz input of the 5790B AC Meaasurement Standard. This is accomplished by characterizing the 5730A's 50 MHz output using a precision thermal voltage converter (TVC), thus reducing uncertainties to calibrate the 5790B.

Compact Power Company
For reliability, all models of the Titan AC Power Sources/Frequency Converters are fully current limit protected against either continuous or transient short circuit or overload conditions. When an overcurrent condition exists, the internal current control loop overrides the voltage control loop and scales back the sinewave drive until it sees a safe output current level.

Radiant Technologies, Inc.
Radiant is introducing an I2C digital-to-analog converter product that can be attached to the Precision Premier II and is controlled from Vision. The addition of this extra voltage source makes it possible for the Premier II to measure the performance of thin-ferroelectric-film gate transistors (TFFTs and MFSFETs). This document explains the theory for such testing and gives examples of such tests using Radiant's SFRAM transistors as examples.

Analog Devices Inc.
Differential amplifiers allow the process of single-ended input to complementary differential outputs or differential inputs to differential outputs. These amplifiers feature two separate feedback loops to control the differential and common-mode output voltages. Analog Devices fully differential amplifiers are configured with a VOCM pin, which can be easily adjusted for setting output common-mode voltage. This provides a convenient solution when interfacing with analog-to-digital converters (ADCs). ADI also offers a series of differential receiver products that convert differential input signals to single ended output.
