Phase signal detecting device |
摘要 |
To detect the phase signal, particularly for alternators of motor vehicles, with simple and inexpensive measures, an active rectifier is employed, which supplies at the output a signal with constant polarity (e.g. positive) which can thus be used to verify the correct operation or malfunction of the alternator.
