TWO-PHASE HARMONIC SIGNAL GENERATOR Russian patent published in 2021 - IPC H03B27/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering, in particular, can be used to generate harmonic excitation signals of sine and cosine windings of rotating transformers. The generator of two-phase harmonic signals contains a trigger, an inverter, a pulse trainer, first and second adders, first, second, third and fourth active second-order low-pass filters, first and second voltage repeaters, first, second, third and fourth negative feedback elements, first, second, third and fourth power amplifiers, block of current limiters, first, second, third and fourth frequency correction elements, first, second, third and fourth snubber chains.

EFFECT: increasing the reliability by providing a high degree of resistance to external influencing factors, in ensuring the identity of the electrical characteristics of the sine and cosine signals of the generator, in ensuring the possibility of connecting a high-capacitive load.
