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.

SCR CONTROLLED DC POWER SUPPLY
PS Series
Variable DC power supplies are AC to DC power supplies with a variable DC output. The output can be varied with an SCR controller. The AC input power can be single phase or three phases. With single phase AC input, the DC output ripple is very high (50%). With three phase AC input, the DC output ripple is low (5%). This would be a key benefit for selecting three phase AC input instead of single phase.
