Integrated EMI/Thermal Design forSwitching Power SuppliesWei ZhangThesis submitted to the Faculty of theVirginia Polytechnic Institute and State Universityin partial fulfillment of the requirements for the degree of Integrated EMI/Thermal Design forSwitching Power SuppliesWei Zhang(ABSTRACT)This work presents the modeling and analysis of EMI and thermal performancefor switch power supply by using the CAD tools. The methodology and design guidelinesare developed.By using a boost PFC circuit as an example, an equivalent circuit model is builtfor EMI noise prediction and analysis. The parasitic elements of circuit layout andcomponents are extracted analytically or by using CAD tools. Based on the model, circuitlayout and magnetic component design are modified to minimize circuit EMI. EMI filtercan be designed at an early stage without prototype implementation.In the second part, thermal analyses are conducted for the circuit by using thesoftware Flotherm, which includes the mechanism of conduction, convection andradiation. Thermal models are built for the components. Thermal performance of thecircuit and the temperature profile of components are predicted. Improved thermalmanagement and winding arrangement are investigated to reduce temperature.In the third part, several circuit layouts and inductor design examples are checkedfrom both the EMI and thermal point of view. Insightful information is obtained.

This article is based in part on Bob Place s ADO is AOK (a simple ADO tutorial). Wrapper Usage This is consist of 2 classes. CDyndb : This Class manages connections and recordsets. Recordsets are organized as linked list (CList) and you can access them using their ids. CDynRec : This class is the node to populate for each recordsets. ADO封装器类 这篇文章一部分基于Bob Place的《ADO is AOK》 (简单的ADO指导) 。 包裹的用法 由2个类组成。 类CDyndb: 这个类别管理连接和记录集。记录集是连接起来的记录的集合，你可以通过他们的ID访问他们。 类CDynRec: 这个类别存放记录集的代码。
