Abstract

A Biryukov Equation is a special case of the Liénard equation. Liénard oscillators are commonly found in scientific literature and they have so many variants. The Biryukov Equation is used to model a set of damped oscillators. Unlike other Liénard oscillators, to the best of our knowledge, there is not a Biryukov oscillator that is experimentally examined in the literature, yet. In this study, a Biryukov oscillator is made using a microcontroller-controlled hand-made optocoupler, a negative impedance converter, and a gyrator. An STM32F070RB is used for the required switching. The oscillator’s operation has been examined experimentally. The optocoupler made of an LDR and a LED placed in a box allows the resistive switching required by a Biryukov oscillator to occur. The experimental results show that the circuit operates as an oscillator and performs well. It is also shown that an underdamped or an overdamped Biryukov oscillator can be made by varying circuit parameters.

Bir Optokuplör Tabanlı Biryukov Osilatörü Tasarımı

Abstract

Biryukov Denklemi, Liénard denkleminin özel bir halidir. Liénard osilatörleri bilimsel literatürde yaygın olarak bulunur ve pek çok çeşidi vardır. Biryukov Denklemi, sönümlü osilatörlerin bir setini modellemek için kullanılır. Bildiğimiz kadarıyla diğer Liénard osilatörlerinden farklı olarak literatürde henüz deneysel olarak incelenen bir Biryukov osilatörü yoktur. Bu çalışmada, mikrodenetleyici kontrollü el yapımı bir optokuplör, bir negatif empedans dönüştürücü ve bir jiratör kullanılarak bir Biryukov osilatörü yapılmıştır. Gerekli anahtarlama için bir STM32F070RB kullanılmıştır. Bu osilatörün çalışması deneysel olarak incelenmiştir. Kutuya yerleştirilmiş bir LDR ve bir LED'den oluşan optokuplör, Biryukov osilatörünün ihtiyaç duyduğu dirençli anahtarlamanın gerçekleşmesini sağlar. Deneysel sonuçlar, devrenin bir osilatör olarak çalıştığını ve iyi performans gösterdiğini göstermektedir. Ayrıca, devre parametrelerini değiştirerek, düşük sönümlemeli veya aşırı sönümlemeli Biryukov osilatörünün yapılabileceği gösterilmiştir.
