Claims

The push-pull generator contains a master oscillator 1 with a push-pull distribution / plug 2 and an OR element, a load 4 and three keys 5 connected in series with each other and a power depletion unit. (. The power sensors 7, 8 of the current pulses are accumulated in power circuits. Trigger output 9 is connected to the i input of the transistor switch 6. One trigger input is connected to the connection point of the push-pull distributor input to the input of the OR element, and the other input is connected to the output of the sensor 7. The trigger output 10 is connected to the input of the transistor switch 5. Od the trigger input is connected to the second output two of the valve and the other is connected to the output of the sensor 8 via the OR element. The push-pull generator operates as follows. At the initial moment of switching on, the signal from the output of the distributor 2 starts through the element OR trigger 10, from the output of which the signal enters the transistor key 5 and turns it on. Due to the resonant nature of the load 4, a sinusoidal current pulse flows through transistor switch 5. Through the half period, the trigger 10 is switched off by a pulse from the pulse distributor 2, and the transistor switch 5 remains open until the excess charge in the base of its transistor has dissipated. After that, the transistor switch 5 is turned off, and a voltage pulse is received from the sensor 7 of the current pulse termination to the input of the trigger 9. This pulse triggers the trigger 9. As a result, a pulse is generated that triggers the transistor switch 6. Thus, the transistor switch 6 is turned on at the moment of current termination through the transistor switch 5. In the next half-period, the generator runs in a similar way. Introduction to the collector circuits of transistor switches of the sensors of the end of current pulses allows to completely eliminate the through currents in the generator when it is operated for varying loads in a wide frequency range.
