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封裝器類 這篇文章一部分基于Bob Place的《ADO is AOK》 (簡單的ADO指導(dǎo)) 。 包裹的用法 由2個(gè)類組成。 類CDyndb: 這個(gè)類別管理連接和記錄集。記錄集是連接起來的記錄的集合，你可以通過他們的ID訪問他們。 類CDynRec: 這個(gè)類別存放記錄集的代碼。
