Control circuit for controlling an electrical power circuit, termed the "circuit to be controlled" (Tp, 40), comprising a stage, termed the "connection/disconnection stage", comprising: - an input port, intended to be coupled to a generator circuit for generating control pulses able to take at least two predefined values associated with distinct control signals to be applied to the circuit to be controlled, - an output port, - means configured to connect its output port to its input port when a control pulse is applied to said input port, and configured to disconnect its output port from its input port when no control pulse is applied to said input port, characterized in that the control circuit comprises a stage, termed the "storage stage", comprising: - a first MOSFET transistor and a second MOSFET transistor, respectively of N type and of P type, gate electrodes of said first and second MOSFET transistors being linked directly together, and source electrodes of said first and second MOSFET transistors being linked directly together, - an input port, coupled to the output port of the connection/disconnection stage, comprising two terminals, one of which is coupled to the gate electrodes and the other of which is coupled to the source electrodes of the first and second MOSFET transistors, - an output port intended to be coupled to the circuit to be controlled, so that, during a disconnection of the connection/disconnection stage: - a signal applied by said connection/disconnection stage just before said disconnection is stored on the input port of the storage stage, - a control signal, associated with the signal stored and received by drain electrodes of the first and second MOSFET transistors (Tm1, Tm2), is applied to the output port of the storage stage as long as said signal is stored. - an input port, intended to be coupled to a generator circuit for generating control pulses able to take at least two predefined values associated with distinct control signals to be applied to the circuit to be controlled, - an output port, - means configured to connect its output port to its input port when a control pulse is applied to said input port, and configured to disconnect its output port from its input port when no control pulse is applied to said input port, characterized in that the control circuit comprises a stage, termed the "storage stage", comprising: - a first MOSFET transistor and a second MOSFET transistor, respectively of N type and of P type, gate electrodes of said first and second MOSFET transistors being linked directly together, and source electrodes of said first and second MOSFET transistors being linked directly together, - an input port, coupled to the output port of the connection/disconnection stage, comprising two terminals, one of which is coupled to the gate electrodes and the other of which is coupled to the source electrodes of the first and second MOSFET transistors, - an output port intended to be coupled to the circuit to be controlled, - a signal applied by said connection/disconnection stage just before said disconnection is stored on the input port of the storage stage, - a control signal, associated with the signal stored and received by drain electrodes of the first and second MOSFET transistors (Tm1, Tm2), is applied to the output port of the storage stage as long as said signal is stored.
