TWO-CYCLE POWER AMPLIFIER Russian patent published in 2016 - IPC H03F3/21 

FIELD: radio electronics.

SUBSTANCE: invention relates to radio electronics and can be used as an amplifier of high power sinusoidal oscillations. In power amplifier with transformer input and output, each arm of which is made on transistor with resistor in emitter, second outputs of resistors in emitters of both arms are connected to common point of the circuit. Collectors are connected to extreme connections of the primary winding of the output transformer, load is connected to its secondary winding. power supply source is connected between middle point of the primary winding of the output transformer and the common point of the circuit. Input signal source is connected to the primary winding of the input transformer. Two additional resistors are included in amplifier circuit. First additional resistor is connected between the first output of the secondary winding of the input transformer and first transistor base, and connection point of first additional resistor and first transistor base is connected to second transistor emitter. Second additional resistor is connected between the second output of the secondary winding of the input transformer and second transistor base, and connection point of second additional resistor and second transistor base is connected to first transistor emitter.

EFFECT: separation of functions of limitation of reverse voltage and control of output power.
