ABSTRACT:
A boost and buck chopper type potential source excitation system for a synchronous type electric power generator which is capable of having an operational characteristic which is better than that of a conventional voltage source excitation system with respect to a rated input voltage and forcing an excitation field by boosting an excitation input voltage using a boost chopper when an excitation input voltage is decreased due to a failure in a cable. The system includes a boost chopper for receiving an output voltage from the buck transformer, converting the thusly received voltage into a direct current voltage, adjusting a level of the same, outputting the same to the thyristor as an excitation voltage, boosting the direct current voltage when the output voltage from the electric power generator is decreased, and outputting the thusly boosted voltage to the thyristor.
