Abstract

The invention relates to a power synthesis technology device of a low-frequency amplifier. The device comprises a power amplifier set, a capacitor set and an isolation transformer set, wherein the power amplifier set comprises power amplifiers from AMP2 to AMPn; the isolation transformer set comprises isolation transformers from T1 to Tn; the capacitor set comprises capacitors from C1 to Cn; the power amplifier set is connected with the isolation transformer set through the capacitor set; the isolation transformer set is connected with an output impedance transformer Rx; and the power amplifier set is connected with a power amplifier AMP1. The invention has the advantages that all the power amplifiers independently output; if a path of amplifiers has abnormality, the path of amplifiers is automatically closed, the output of the path is subjected to a short circuit, and the amplifiers still can normally work; during maintaining, the path is changed, thus the repeated design of the amplifiers of the same type can be reduced, thereby the cost is saved, and the modular design of the power amplifiers is realized; and the device is convenient to produce.

Description

technical field [0001] The invention relates to the field of amplifier power synthesis, and mainly relates to a low-frequency amplifier power synthesis technology device for increasing the output power of a power amplifier. Background technique [0002] Electronic technology has developed by leaps and bounds in recent decades, and more and more digital technologies have replaced analog electronic technology. Some people once said that analog electronic technology will withdraw from the stage of electronic technology. In recent years, people have become more and more aware of analog electronic technology, and many places cannot do without it, especially in the power amplification of AC signals. In recent years, domestic low-frequency amplifier technology has also become more and more mature. At present, there are triode emitters or FET source parallel push-pull outputs (OCL power amplifiers), which use BTL amplifier circuits to increase output power and improve amplifier effi...
