Document Type and Number:
WIPO Patent Application WO/2018/107987
Kind Code:
A1
Abstract:
A current detection device (1), a current detection system and a current detection method, the current detection device (1) comprising a current signal port, a first sensing device (11) and a second sensing device (12), wherein: the first sensing device (11) detects a current flowing through the current signal port and obtains a first current detection signal; the second sensing device (12) detects a current flowing through the first sensing device (11) and obtains a second current detection signal, wherein the first sensing device (11) is a shunt resistor, and the second sensing device (12) is a Hall-effect current sensor or a fluxgate sensing device; and a controller (2) in the current detection system processes the first current detection signal and the second current detection signal to obtain a final detection signal.
