Patent number: 7061733Abstract: A power supply cut-off circuit for breaking a connection between a power rectifier and a power supply line leading to a load. The cut-off circuit is adapted to be connected between the power rectifier and the power supply line and includes a switching circuit connected to a control circuit. The control circuit is operable to sense a malfunction in the power rectifier and to use the switching circuit to disconnect the power rectifier from the power supply line. In one embodiment, the switching circuit includes a plurality of MOSFETs connected in parallel with one another and the control circuit disconnects the power rectifier from the power supply line by making the MOSFETs non-conducting when the power rectifier malfunctions and the output current of the power rectifier becomes inverted.Type: GrantFiled: March 28, 2003Date of Patent: June 13, 2006Assignee: Magnetek S.p.A.Inventors: Antonio Canova, Lorenzo Cincinelli, Mauro Piazzesi
