Bu makalede, değişken bir çıkış gerilimi ve kademeli olarak değişen frekansı elde etmek için tek fazlı matris dönüştürücü ile birlikte Z-kaynak ağı kullanılan alternatif akım-alternatif akım (AA-AA) yapısı incelenmiştir. yapısında, hem düşürülebilmekte de yükseltilebilmektedir. Matris dönüştürücü, doğrudan AA-AA dönüşüm yaparken anahtarlama stratejisi frekansını değiştirme imkânı sağlamaktadır....

This paper explores Switched Inductor (SL) Quasi Z-source Inverter which has high boost factor and performance when compared to other Z-Source inverters along with three control methods: simple boost, maximum boost and maximum constant boost. The proposed inverter improves the input current, reduces the passive count and also the reliability. The simulations are done in MATLAB/Simulink environm...

The present work proposes Z-Source Inverter and Push-Pull Inverter based STATCOM for the control of r...

Linux is gaining interest as a solution across many hardware platforms: Intel based machines, Sun and Apple proprietary hardware and IBM zSeries platforms. But once applications are ported to an open source operating system what options are available to monitor their performance and availability? This presentation covers native Linux solutions to monitoring performance and collecting statistics...

This technical report presents the design of a Z-source inverter for an electric bike controller. The objective of this work is to evaluate the potential of using this non-standard inverter topology for a medium power (250W 3kW) motor drive application. The Z-source inverter is able to use the shoot-through state to boost the dc bus voltage, which enables a permanent magnet motor to achieve a h...

The Neutral Point Clamped (NPC) three-level inverter with Z-source network is a relatively recent converter topology that exhibits both voltage-buck and voltage-boost capability. This concept can be applied to all acto-ac, dc-to-dc, ac-to-dc, and dc-to-ac power conversion whether two-level or multilevel. However, multilevel inverters offer many benefits for higher power applications. Existing p...

Abstract: This paper proposes an improved pulse-width modulation (PWM) strategy to reduce the capacitor voltage ripple in Z-source wind energy conversion system. In order to make sure that Z-source capacitor voltage has symmetrical maximum and minimum amplitudes in each active state, the shoot-through time is divided into six unequal parts. According to the active state and zero state, the shoo...
