摘要： The circuit arrangement comprises a driver stage and a control circuit coupled to the control input of a switching transistor. The driver stage provides a switching voltage for the operation of the switching transistor, and the control circuit provides a shaping of the switching voltage in the sense of delaying the switching through of the switching transistor. The control circuit comprises in particular a control transistor, which is coupled a control input via a high pass filter to the output of the driver stage and with an current input to the control input of the switching transistor. The switching transistor is for example a MOSFET being used for switching on and off a capacitive load.

摘要： The battery-operated power supply unit, which comprises a switching transistor whose current terminals are connected in series with a battery, in the current path of the power supply unit, comprises a protective circuit, which is arranged across the current terminals of the switching transistor and evaluates the differential voltage across the switching transistor. The switching transistor is in particular a MOSFET with a parallel-connected internal diode. In the event of too high a differential voltage, the power supply unit or an appliance connected downstream is switched off, so that the switching transistor is not destroyed in the event of a fault. The protective circuit contains, in particular, a threshold circuit with a transistor whose base and emitter are connected across the current terminals of the switching transistor and whose base bias voltage is set via a voltage divider in such a way that, in the event of too high a differential voltage, the transistor switches on and, in this way, triggers a turn-off signal via the collector.

摘要： A line deflection circuit for a television receiver or a switched-mode power supply operate with a switching transistor that is connected in series with the primary winding of a transformer and is periodically switched on and off by a switching voltage. In such a circuit, appreciable turn-on and turn-off losses, which reduce the overall efficiency of the circuit, are produced at the switching transistor, particularly at higher operating frequencies. Within a control circuit a DC voltage source is connected to the base of the switching transistor via a periodically actuated switch element and a coil having a core and a tap. The two parts of the coil are wound in opposite senses, and the tap is connected via a diode to ground or to the emitter of the switching transistor. The control circuit further includes a charge-reversal path via which, during a demagnetization phase of the coil, the energy stored in the coil in the form of a current is transferred in the form of a negative voltage to a capacitor that is coupled via a second diode to a first part of the coil. The negative voltage is applied during a residual time subsequent to the demagnetization phase as a reverse voltage to the base of the switching transistor.

摘要： A switching power supply includes a switching transistor coupled to a winding of a first transformer for generating a collector current. The collector current is coupled in a current path that includes that winding and a primary winding of a power transformer. The collector current is coupled to the base of the switching transistor via the first transformer such that when the switching transistor is conductive, both the collector current and a base current of the transistor are upramping. When the transistor is nonconductive, a horizontal synchronizing signal is coupled via the first transformer to synchronize the base current.
