AMPLITUDE DETECTOR OF HARMONIC AND NONHARMONIC ELECTRIC SIGNALS Russian patent published in 2010 - IPC H03D3/00 

FIELD: electricity.

SUBSTANCE: in amplitude detector (AD) of harmonic and nonharmonic electric signals (ES), made of vessel and high electric capacitance capacitor (HECC), there is a bridge rectifier introduced, which is arranged on four semiconductor diodes, providing for charge of this HECC to maximum positive value of pulsating voltage relative to vessel, highest value of which is practically equal to ES amplitude, and circuit of this capacitor quick discharge torque control, including serially connected Schmitt trigger, gate multivibrator, differentiating circuit, inverter, resistor and electronic switch, besides input of Schmitt trigger is connected to the first diagonal of bridge rectifier, which is its input, output of bridge rectifier, its second diagonal is connected to HECC, capacitance filter, outlet of the latter is connected to load and via resistor to collector of powerful transistor of electronic switch, and emitter of which is connected to vessel of AD of harmonic and nonharmonic ES, emitter of powerful transistor of electronic switch is connected to AD vessel, inverter vessel, Schmitt trigger, differentiating circuit, gate multivibrator and lower facing of HECC are connected to vessel of AD of harmonic and nonharmonic ES.

EFFECT: accuracy improvement.
