A diode rectifier is the lowest cost and most simplistic type of exciter. This type of exciter is a combination isolation transformer with numerous taps and a non-regulated diode rectifier. The voltage output of the rectifier is a direct ratio of AC input to DC output. The exciter output voltage can only be adjusted by changing transformer taps. The current passed to the field is a function of the exciter voltage and field resistance (Ohm’s law E=IR). The transformer taps can only be changed with the motor and exciter off line. Standard taps provided are five 5% full current capacity taps below the nominal voltage. Total of six taps provided. Kinetics manufactures all our own transformers, with copper conductor as our standard, from 1 to 2000 KVA up to 15 KV class. Providing additional taps to the primary or secondary of the transformer is an available customer option.
