Js Chitode Power Electronics Pdf 237l



Introduction




What is power electronics?




Power electronics is a branch of electrical engineering that deals with the conversion, control and application of electrical power using electronic devices that operate in the switching mode. These devices are called power semiconductor devices, such as diodes, transistors, thyristors, MOSFETs, IGBTs and more. Power electronics can handle high voltages, currents and frequencies, and can improve the efficiency, performance and reliability of power systems.


Who is Js Chitode?




Dr. J. S. Chitode is a professor of electronics engineering at Pimpri Chinchwad College of Engineering in Pune, India. He has more than 25 years of teaching experience and has authored several books on electronics subjects such as digital signal processing, communication engineering, microprocessors and microcontrollers, analog communication systems and power electronics. He has also published many research papers in national and international journals.


What is the book about?




The book Power Electronics by Dr. J. S. Chitode is a comprehensive textbook that covers the theory and practice of power electronics for undergraduate students of electrical and electronics engineering. The book is divided into five chapters: power semiconductor devices, DC-DC converters, phase controlled converters, AC voltage controllers and inverters. The book explains the concepts with clear diagrams, examples, solved problems and exercises. The book also provides references for further reading and appendices for additional information.


Power Semiconductor Devices




Types and characteristics of power devices




The first chapter of the book introduces the types and characteristics of power semiconductor devices such as BJT, SCR, MOSFET, IGBT, MCT, GTO and TRIAC. The chapter explains the structure, operation, switching characteristics, ratings and specifications of each device. The chapter also compares the advantages and disadvantages of different devices for various applications.


Protection, cooling and mounting of power devices




The second section of the chapter discusses the protection, cooling and mounting of power devices. The section explains the various methods of protecting the devices from overvoltage, overcurrent, overtemperature and other faults. The section also describes the techniques of cooling the devices using heat sinks, fans and liquid cooling. The section also covers the aspects of mounting the devices on printed circuit boards, modules and packages.


Series and parallel operation of power devices




The third section of the chapter covers the series and parallel operation of power devices. The section explains the reasons and methods of connecting the devices in series or parallel to increase the voltage or current handling capability. The section also discusses the problems and solutions of series and parallel operation such as voltage sharing, current sharing, commutation and snubber circuits.


DC-DC Converters




Step-up and step-down choppers




The second chapter of the book deals with DC-DC converters, also known as choppers. These are power electronic circuits that convert a fixed DC input voltage to a variable DC output voltage. The chapter explains the principle and operation of step-up and step-down choppers, which can increase or decrease the output voltage respectively. The chapter also derives the expressions for the output voltage, current and power for different types of choppers.


Control strategies and classification of choppers




The second section of the chapter describes the control strategies and classification of choppers. The section explains how to control the output voltage of choppers by varying the duty cycle, frequency or phase angle of the switching device. The section also classifies the choppers into four types based on the direction of current flow: type A, type B, type C and type D. The section also gives examples of applications of each type of chopper.


Phase Controlled Converters




Single and three phase half/full bridge converters




The third chapter of the book covers phase controlled converters, which are power electronic circuits that convert a fixed AC input voltage to a variable DC output voltage. The chapter explains the principle and operation of single and three phase half/full bridge converters, which use thyristors as switching devices. The chapter also derives the expressions for the output voltage, current and power for different types of converters.


Effect of source impedance and dual converters




The second section of the chapter discusses the effect of source impedance and dual converters. The section explains how the source impedance affects the performance and stability of converters, and how to compensate for it using filters or transformers. The section also describes the concept and operation of dual converters, which can provide bidirectional power flow between AC and DC sources.


AC Voltage Controllers




On-off and phase control operation




The fourth chapter of the book deals with AC voltage controllers, which are power electronic circuits that convert a fixed AC input voltage to a variable AC output voltage. The chapter explains the principle and operation of on-off and phase control operation, which use triacs as switching devices. The chapter also derives the expressions for the output voltage, current and power factor for different types of controllers.


Single and three phase controllers and cycloconverters




The second section of the chapter describes the single and three phase controllers and cycloconverters. The section explains how to control the output voltage of controllers by varying the firing angle or conduction angle of triacs. The section also classifies the controllers into four types based on their configuration: single phase half wave, single phase full wave, three phase half wave and three phase full wave. The section also introduces cycloconverters, which can convert AC input voltage to AC output voltage with different frequency.


Inverters




Series inverter and bridge inverter




The fifth chapter of the book covers inverters, which are power electronic circuits that convert a fixed DC input voltage to a variable AC output voltage. The chapter explains the principle and operation of series inverter and bridge inverter, which use transistors or thyristors as switching devices. The chapter also derives the expressions for the output voltage, current and harmonic distortion for different types of inverters.


Quasi square wave inverters and push-pull inverters




The second section of the chapter describes quasi square wave inverters and push-pull inverters. The section explains how to improve the output waveform quality of inverters by using multiple switches or transformers. The section also discusses quasi square wave inverters, which can produce quasi sinusoidal output waveform by using pulse width modulation (PWM) technique. The section also introduces push-pull inverters, which can produce high frequency AC output by using two transistors in push-pull configuration.
