최근 에너지 자원의 고갈과 환경 파괴 문제로 인해 다양한 분야에서 에너지 절약에 대한 이슈가 증가하고 있다. 다양한 산업 응용분야에서 AC?AC 전력변환 시스템이 사용되며, 가장 많이 사용되는 토폴로지는 AC?DC?AC 간접 전력변환 방식의 백투백(Back?to?Back) 컨버터이다. 백투백 컨버터는 교류를 직류로 변환하고, 다시 직류를 교류로 변환하여 가변 전압 및 가변 주파수의 AC?AC 전력변환을 수행하며, 두 개의 인버터와 커패시터나 인덕터와 같이 부피가 큰 에너지 저장 소자를 갖는 직류단으로 구성된다. 이러한 백투백 컨버터는 수명이 짧다는 치명적인 단점이 있어, 이의 대안으로 매트릭스 컨버터(Matrix Converter)에 대한 연구가 진행 중이다. 이 책에서는 매트릭스 컨버터의 구조 및 변조 방법 등에 대하여 이론적으로 살펴보고, 다양한 매트릭스 컨버터의 제어 방법에 대해 다룬다. 산업용으로 널리 쓰이기 위해 극복해야 할 문제점들에 대하여 다루며, 매트릭스 컨버터 구동의 주요 관심사를 살펴보고 최신 기법을 정리한다.

A novel cascaded multilevel converter is discussed in this book. The book discusses an innovative approach to produce more voltage levels from fewer H- bridges in the cascaded multilevel converter. The converter uses fewer H-bridges and the proposed switching scheme renders more voltage levels in the staircase waveform with equal steps. Since the resulting voltage levels are equal, the angles are determined for the complete elimination of more unwanted harmonics.

The world energy consumption is expected to increase substantially in the next decade and if the same negligence towards the environment continues, there will be a day when no clean air would be available. Electricity Generation has become a critical problem in the modern era as the traditional energy resources are not getting replenished and there might be a day where there may be no energy for use. People are looking for better conversion devices.

The task of this project work is to model a buck converter and a measurement system to sense the inductor current and output voltages of the buck converter system of Ericsson's BMR450. Such that the measurements of inductor current and output voltage can be sampled with 5MS/s and properly calibrated for BMR450 and get connected to the PCI-6111. Different current sensing techniques are analyzed and the chosen technique is modeled and simulated.

DC/DC converters provide stable output voltage and variable output current. It is used to maintain a steady, stable voltage as a power supply for semiconductor devices. DC/DC converters are a necessity for almost all electronic devices and are used to maintain a constant output voltage regardless of minor variations in input voltage or load current. Modeling and simulation is the instrument used to shape the system level analysis and obtain better performance of the converters.

This book presents the small-signal ac modeling and closed loop control of three-phase interleaved and three stage converter. The multi-phased dc-dc converters contain several parallel power stages, with unique voltage mode controlled loop to attain the desired output voltage. State-space modeling methodology has been adopted to have linearized small-signal ac equivalent model of the converter.

Stability is a prime concern in any dc voltage regulation system. However, closed-loop stability is not always guaranteed if a low-pass filter is present at dc-dc converter input. In this thesis small-signal transfer functions based on averaged modeling techniques are exploited to systematically formulate some design rules to avoid instability.

Stringent emission regulations around the world necessitate the use of high-efficiency catalytic converters in vehicle exhaust systems. Therefore, determining the optimum geometry of the honeycomb monolith structure is necessary. This structure requires a high surface area for treating gases while maintaining a low pressure drop in the engine. In this book, an adapted sub-grid scale modeling is used to predict the pressure loss of square- and hexagonal-cell-shaped honeycomb monoliths.
