POWER AMPLIFIER WITH OVERCURRENT PROTECTIVE GEAR |
摘要 |
power amplifiers. SUBSTANCE: amplifier is provided with positive feedback applied between load output and its input; amount of positive feedback equals that of negative feedback; minimal amount of the latter beta is found from equation , where K is gain factor; Z is load impedance; R is rating of resistor inserted in series with amplifier output circuit; Π is permissible overcurrent factor of amplifier. EFFECT: reduced distortions brought in by protective gear and improved reliability of the latter. 3 dwg
