Figure appliance repair school (2) is a plug-cooker school repair. the revised version. The book to the United States. the two brands Pentium cooker. for example. from the understanding of components. circuit analysis study began. progressive approach to introduce a special induction failure and failure of common maintenance methods. in particular. introduced the principle of single-chip cooker and maintenance methods. highlighting the practicality of maintenance. easy to readers to judge the whole. Figure Studies Revised Induction (2) the use of digital camera technology. a true shooting of maintenance tools. components. circuit board form. content and popular. intuitive. easy to understand illustrations. In addition. the appliance repair Figure Studies (2) Appendix provides a large number of induction cooker in the circuit diagram and maintenance of data for easy queries. Figure Studies Revised Induction (2) for household appliances maintenance personnel to read and learn. Contents: Chapter 1. the type of appliance. construction and use of the development process of an induction cooker. types and properties of the construction of section 2 of a cooker. shell composed of two internal electrical structure of three or four machine cooling. the general structure of induction cooker monitoring software Section 3. a circuit of induction cooker. the main power input unit two. three inverter modules. synchronous control unit four.
