ABSTRACT:
A blocking oscillator converter with controlling logic system has an oscillator which, in the active state, blocks control of a switching transistor of the converter, and hence feeding of the electronic apparatus to be supplied by the converter. The oscillator blocks the output of a control circuit in the active state and, in the passive state, has no influence on the control of the switching transistor by the control circuit. The active state of the oscillator is triggered by monitoring of the possible operational errors by an error indicator when such an operational error occurs. After decay of the operational error has taken place, the oscillator again returns to the passive state. The advantage of the blocking oscillator converter with controlling logic system is primarily provided through a considerable reduction of the power dissipation in the blocking oscillator converter, and primarily in its switching transistor during error indications.
