Title: Current overload detector for DC voltage regulator - uses ferromagnetic core with detection winding surrounding current carrying output conductor
Inventor: HAMON JEAN
IPC: H02M3/156
Filed: 1975-02-20
Abstract: The circuit for detecting variations in a DC current uses a ferromagnetic core, surrounding the conductor carrying the current. The core is provided with a detection winding, supplied with a rectangular voltage and the sawtooth current waveform for the winding is compared with a preset reference. A variation in the current along the conductor passing through the centre of the core, produces a variation in the inductance of the detection winding and hence a variation in the maximum amplitude of the sawtooth current waveform. When the latter maximum amplitude is above the preset reference a blocking signal is pref. supplied for the regulating circuit for the DC current.
