Abstract (en)
[origin: WO2009071173A1] 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 for 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 surpressed when the voltage on the output of the blocking oscillator is too high. A power monitoring circuit functions independently from the oscillator and the voltage monitoring circuit and surpresses the impulses for the power transistor when the flow on the output side exceeds a predetermined measurement.
