Design of a two-phase PMSM fed by an AC-AC converter

Abstract

A two-phase permanent magnet synchronous motor is designed for using an AC-AC converter drive system fed from a single-phase source. This motor and drive system are proposed to replace with a traditional single-phase motors fed by electricity grid for improving the efficiency of the system. The proposed AC drive system can be connected directly between AC grid and motor without requiring any storage device such as DClink large capacitors and rectification. The structure of AC-AC converter and modulation technique is presented with vector controlled two-phase PMSM. The converter output voltage and current waveforms and harmonic contents are analyzed with MATLAB simulation program. Additionally, responses of the motor speed and torque are presented for various conditions.

Design and implementation of two‐phase permanent magnet synchronous motor fed by a matrix converter

“…The switching frequency of the other switches depend on the reference signal frequency which is variable with desired output voltage signal. The frequency of Reference A signal is related to the sum of the input and output converter frequency as given in (1). In addition, the frequency of Reference B signal has π/2 shift as given in (2) [1].…”

“…The frequency of Reference A signal is related to the sum of the input and output converter frequency as given in (1). In addition, the frequency of Reference B signal has π/2 shift as given in (2) [1]. The References A and B determine the output voltage waveform for the stator supply voltage requires two voltages with 90° shifted phase between them…”

“…Electric motors have a significant impact on the total electric power consumption in both domestics homes and industrial applications. Especially, the single-phase induction motor with squirrel-cage rotor is one of the most widely used in low-power applications, home appliances and many applications wherever there is a single-phase main [1][2][3]. On the other hand, the single-phase induction motor has some disadvantages such as low efficiency, low power/volume and inability to start without any kind of equipment such as capacitor, auxiliary winding, centrifuge-switch etc.…”

İki-Fazlı AC-AC Çeviricinin Tasarımı ve Gerçekleştirilmesi

“…Daha önceki bu çalışmalarda, ayarlanabilir tek faz çıkışı üretmek için sadece iki bacaklı yapı kullanılmıştır [16]. Bu çalışmalara ek olarak tek fazlı şebekeden iki faz elde edebilmek için ekstra bir bacak daha eklenmiş ve yeni bir anahtarlama algoritması benzetim sonuçları ile test edilmiştir [21]. Bu makalede, [21]'de yazarlar tarafından önerilen anahtarlama algoritması ilk olarak deneysel sonuçlar ile desteklenmiştir.…”

Tek Fazlı Matris Dönüştürücünün Frekans Değiştirici Olarak Çalışması

“…Modülasyon tekniğine bağlı olarak giriş ve çıkış akım dalga şekilleri sinüzoidaldir. Harmonikler sadece anahtarlama frekansı civarındadır ve giriş filtre gereksinimleri minimumdur [4,[8][9][10][11][12].…”
