Maqolada hiziqsiz elektromagnit zanjirlarda hosil bo‘ladigan avtoparametrik tebranishlarni chastotaviy-energetikusulga asosan tahlil qilish mumkinligi ko‘rsatilgan. Nochiziqli elektr zanjirlar uchun oniy quvvat qiymatiga mos holdachastota o‘zgartirgich xususiyatini miqdor va sifat jihatdan xarakterlovchi quvvatlar muvozanati tenglamasi keltirilgan.

The paper discusses the possibilities of using the frequency-energy approach for analyzing the frequencytransformingproperties of non-linear electromagnetic circuits of autoparametric nature. For nonlinear electricalcircuits, according to the instantaneous power theorem, a power balance equation is derived that characterizesqualitative and quantitative estimates of frequency converters.
