Diagnostic system for measuring current/voltage of electric generator in e.g. hybrid vehicle, has hybrid measurement module connected to separate digital processing module, and amplifiers receiving signals of giant magnetoresistive sensors

摘要

The system has a hybrid measurement module with giant magnetoresistive current/voltage sensors (111-118) integrated on a same strip (100), and connected to a separate digital processing module (400). The measurement module has a printed circuit with an amplifying module (200) whose set of amplifiers (201-208) receives signals delivered by the sensors, and another printed circuit with a multiplexing module (300). The circuits are assembled with input-output connection terminals connected to signal exchange tracks formed on sections of the circuits and connected to connection devices (401, 402).
