POWER AMP extremely low frequency (ELF) range

摘要

Power amplifier ELF range, comprising a rectifier, the input filter and oscillator thyristor comprising a single-phase inverters connected to the high-frequency transformer, the secondary windings of which through the diode rectifier bridges connected in series with the switch, the input filter and the load, characterized in that, in order to simplify the device , bandwidth extension, and improve reliability further introduced two control devices forming the inverter and the exciter frequency, wherein the first sound control -governing device is connected to the first input of the rectifier, which second input is coupled to the transformer, and the third input - single-phase inverter which is connected to a first input of a pathogen formation frequencies and a second input - the transformer (T) (load), which first input is connected to single-phase thyristor bridge, the second input - to a second control device, and the third input - to matching device through a low-pass filter, wherein the matching device is connected to the antenna.
