The outputs carrying pulse voltages (V4,V5) feed them to a connected transformer (10) secondarily coupled to a pulse former (N1) connected to the transistor (Q1) control. The pulse former (N1) comprises a diode rectifier bridge connected to the transformer (10), with a storage capacitor, the direct current voltage output of which is connected to an amplifier fed with DC. The amplifier output controls the transistor, and its input is directly coupled to one end of the transformer sec. voltage, to which also a capacitor is connected, the other end of which passes to one direct current coil. - The transformer partly transmits commands covering pulse start and stop via its rising and falling flanks to the pulse former and partly can transmit energy for feed of the pulse former, the latter thereby produces a desired rectangular curve form on the transistor control. |
