First of all, this paper gives a brief introduction to the basic theory of induction heating and outlines the development and the status of the induction heating technique, mainly about the theory and practical realization of full-bridge series resonant induction heating inverter.
    Chapter 1 gives a brief introduction to the basic theory of induction heating, then outlines the development and the status of the induction heating technique, and presents the actual meaning of the research and the main content of this paper.
    Chapter 2 compares the differences of the current-fed converter and the voltage-fed converter used in induction heating power, and give a special focus on the voltage-feed converter ,These content is the base of all the following chapters,and is the guideline of the project I did.
    Chapter 3 gives the topology of the main circuit on the base of meeting the request of this project,and also the parameters for the most important components in the circuit.
    Chapter 4 gives the important protection and controlling part of this project and their final design.
    Chapter 5 presents one common problem which happens in series resonant induction heating inverter ,then made much deep theorical analysis in order to resolve this problem.
    Chapter 6 analyzes the result of the experiment and verifies the
    
    
    feasibility of the whole plan in IGBT series resonant inverter of induction heating.
    At the end of this paper, a brief summation for the whole dissertation is giveno
