Abstract:
A compressor control device includes a driving circuit (7a), for controllably supplying a coil (4a) of an electric motor (4) of a compressor (2). A temperature sensor (11) is thermally coupled to the driving circuit (7a) and provides a temperature sensing signal (V T ) correlated to a temperature (T) in the driving circuit (7a). A control stage (8, 9, 10), coupled to the driving circuit (7a) and to the temperature sensor (11), selectively prevents the driving circuit (7a) from supplying the coil (4a), in response to a minimum temperature increment (ΔT) being detected by the temperature sensor (11) within a pre-determined control time window (Δτ).
