Transistor Blocking Oscillator

The transistor blocking oscillator has a circuit for compensating stray pulses applied to the load side.

The series connection of feedback transformer winding W3 and the collector path of transistor T has connected in parallel to the series connection of oppositely wound winding W4 and condenser Ck. Condenser Ck is selected to correspond to the collector capacity Cc of T.

Windings W3 and W4 have the same number of turns. All stray. pulses reaching the blocking oscillator from the load side L now split up at point A into two equal parts. This is due to the symmetric arrangement of the two current paths they encounter. The two partial currents cancel each other with respect to their effectiveness in magnetizing the core of the feedback transformer.
