Crowbar Resistors
-
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.

ECU Calibration
-
Designing an Electronic Control Unit (ECU) is only the beginning. The features in ECUs, such as Powertrain Control Units, are quickly becoming more complex and offering more features. Thousands of variables are now provided for the engineer to modify during the in-vehicle calibration phase, and fine tuning them is as complicated as it is critical. Calibration tools significantly impact the efficiency and effectiveness of the ECU development process. These tools are typically comprised of PC-based software to perform the adjustment of the variables and an ECU hardware interface to provide the connection of the software to the controller. Teams must be able to measure and time-align relationships of inputs and outputs and make real-time modifications.
