    • A circuit arrangement for enforcing an intrinsically safe situation in a hazardous zone features a first switching device that lies in the series arm and a second switching device that lies in the shunt arm. If a fault occurs that would violate the conditions of intrinsic safety, the first switching device is initially blocked and the second switching device is switched through with a time delay such that the output terminals are mutually short-circuited. In addition, a monitoring device is provided for monitoring the load conditions at the switching device arranged in the series arm.

    • According to the invention, a blocking oscillator type converter circuit functions with a transformator that only comprises a primary winding and a secondary winding. Said transformator does not comprise a return coupling winding for the blocking oscillator. The control voltage of the oscillator is derived from the primary voltage of the transformator during the free-wheeling phase. The invention also relates to a voltage monitoring circuit that works independently from the oscillator, the output voltage of the oscillator being repressed when the voltage on the output of the blocking oscillator is too high. A flow monitoring circuit functions independently from the oscillator and the voltage monitoring circuit and suppresses the impulses for the power transistor when the power on the output side exceeds a predetermined measurement.

    • A power-supply includes a power-supply input. A transformer has a primary winding and a secondary winding separated galvanically from the primary winding. A controlled semiconductor switch has a control input in series circuit with the primary winding, which lies parallel to the power-supply input. A controllable control circuit for the semiconductor switch delivers a periodic control signal, which is controlled such that the output voltage on the secondary winding is kept at a desired value independent of the load, to the semiconductor switch. A voltage limiting circuit lies parallel to the input side of the primary winding. An output signal of the voltage limiting circuit acts on the switch state of the semiconductor switch to move the semiconductor switch to a stationary state, in which it generates no alternating current on the primary winding, when the voltage on the primary winding has exceeded a specified limiting value.
