Abstract : The impact on a prime power source due to AC resonant charging was investigated. The source was a standard DOD 15 KW, 400 Hz alternator. Adverse impact on the alternator was almost negligible for a varying load of 15 to 60 KW and a frequency change of 380 to 475 Hz. The only exception was caused by the pulser diodes. Their turn-on was reflected in the alternator voltage waveforms. An indirect approach is presented for determining resonance and, thus, the internal reactance contribution by the alternator. This value was found to be slightly less than that specified for the leakage reactance. The investigation concludes that resonance, in the classical steady state sense, is never reached. Even though the charging circuit has a transient response, the alternator armature reaction is approximately fixed. This implies that the alternator is in a near steady state mode of operation.
