FIELD: electricity.
SUBSTANCE: invention relates to electrical engineering and can be used in power amplifiers. Electric signals amplification device comprises two groups of inductance coils, electric motor driven disc for resonant circuit installed in gap between coils parameters periodic change, which are connected in pairs in series between each other and with capacitor and form high-frequency Tesla resonance transformer primary winding resonant circuit, which secondary winding is formed by each inductance coil additional windings. Method of electrical signals amplification is characterized by that vibrations excited in resonance circuit are converted by voltage in said Tesla transformer, rectified and transmitted to load through inverter.
EFFECT: higher gain coefficient and reduced dependency of electric signals amplification parameters from load.
