  • Patent number: 4801821
    Abstract: Integrated bistable electronic commutator comprising a switch provided with at least two terminals, said switch incorporating at least one MOS power transistor (8); a MOS technology control circuit (10) having a bistable flip-flop provided with an input for setting to "1" and an input for setting to "0" and at least one control output, each control output being connected to the gate of at least one MOS power transistor of the switch; an integrated power supply (12) for supplying said circuit; and two optical couplers (14, 16) which in each case receive an electrical commutating control signal and which in each case transmits said signal to one input of the control circuit, each optical coupler ensuring an electrical insulation of the commutator. The invention relates to bistable commutators of the open-closed and rest-working type, which are monodirectional and bidirectional, for direct current and for alternating current.
