Title: Diagnostic circuit for vehicle mounted three phase generators - uses waveform analysis circuits to locate faulty components
Inventor: BREMER WOLFGANG DIPL ING
IPC: G01R31/00
Filed: 1975-11-18
Abstract: A diagnostic circuit is for fault finding in the three phase generator systems of vehicles, which usually produce a direct voltage via suitable rectifier bridges, and uses automatic waveform analysis circuits to detect faulty components. Maintenance efficiency in such vehicles is improved, particularly when the generating equipment is relatively inaccessible. A typical vehicle generator consists of a three phase generator with star connected generating windings (4) feeding a six diode rectifying bridge (5, 6) to produce a direct voltage which charges the battery (7) and also drains a control circuit (10) which in turn feeds the generator field winding (2). Different speed voltage characteristics and output waveform shapes correspond to different faults in this network, and the output is analyzed. A number of different analysis circuits, including logic flipflops, bandpass filters, amplifiers and waveform squaring circuits are described. Essentially, these detect the various harmonic components in a faulty network and indicate corresponding faulty components.
