摘要： An operating mechanism for an aircraft door performs all the door motions and locking operations for the opening and closing of the door with the aid of electric motors which operate the respective elements of the mechanism through gear drives or through spindle drives to provide the power or torque moment for the respective motion. The motion sequence of the door operation is stored as a respective program in a memory of a central processing unit which in turn operates the electric motors in accordance with the programs. Operator initiated control signals are also provided to the central processing unit through respective panels. The pressurization and depressurization of the aircraft cabin is integrated into the door control so that pressurization cannot take place unless the doors are fully closed and locked and so that door opening cannot take place until depressurization is completed.

摘要： A direct-voltage flyback converter includes a primary winding of a transformer in series with the switching path of a controllable switch which is connected in turn to a control device (P). A first capacitor (C1) in series with a first diode (D1) is connected in parallel with the transformer primary winding (N1). A series circuit consisting of a first coil (L1), a second diode (D2) and the first capacitor (C 1) is connected in parallel with the switching path. In order to regulate the output voltage of the switched-mode direct-voltage flyback converter accurately and with low losses, and without the control device being activated from the secondary side, a sensing circuit (M) and a demagnetization circuit (A) are connected to the control device (P). A winding (N3) of the transformer (Tr) is connected in the sensing circuit (M) and a second coil (L2), coupled to the first coil (L1), is connected in the demagnetization circuit (a). The second coil provides demagnetization by transferring energy stored in the first coil into the demagnetization circuit.

摘要： In a circuit arrangement for limiting the switching-on current peaks in a switching transistor (T), for example, a switching transistor in a direct voltage converter, rectangular switching pulses of the same height (UST) are applied to the control input of the switching transistor. In order to protect, for the largest possible number of types of application, the switching transistor (T) having an equally dimensioned coil (PW) from overload, the coil is included in a branch which is common both to the control circuit and to the operating circuit of the switching transistor. For simultaneously monitoring the operating current (I) in a direct voltage converter (UB, UA), the coil is the primary coil of a current transformer (STW), whose secondary circuit includes, inter alia, the series-combination of a saturable choke (DR) and a load resistor (RB2). The proportioning of all elements (RB1, DR, RB2, SW) in the secondary circuit of the current converter transformer can be chosen so that the voltage drop at the load resistor (RB2) is a measure of the current strength (i) through the switching transistor. When this voltage drop exceeds a threshold, the switching transistor is cut off by a pulse width modulator (PWM) until the next switching pulse occurs.
