  • 如何設計升壓轉換器MAX17597峰值電流模式控制器

    Abstract: This application note describes how to design boost converters using the MAX17597 peakcurrent-mode controller. Boost converters can be operated in discontinuous conduction mode (DCM) orcontinuous conduction mode (CCM). This operating mode can affect the component choices, stress levelin power devices, and controller design. Formulas for calculating component values and ratingsare alsopresented.

  • 開關電源EMI設計(英文版)

    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.

  • 開關電源EMI整改經驗分享

    EMC的分類及標準:EMC(E1ectromagnetic Compatibility)是電磁兼容,它包括EMI(電磁騷擾)和EMS(電磁抗騷擾)。EMC定義為:設備或系統在其電磁環境中能正常工作且不對該環境中的任何設備的任何事物構成不能承受的電磁騷擾的能力。EMC整的稱呼為電磁兼容。EMP是指電磁脈沖。EMC=EMI+EMS EMI:電磁干擾EMS:電磁相容性(免疫力)EMI 可分為傳導conduction及輻射Radiation兩部分,conduction規范一般可分為:FCC Part 15J Class B;CISPR 22(EN55022,EN61000-3-2,EN61000-3-3)Class B;國標IT類(GB9254,GB17625)和AV類(GB13837,GB17625)。FCC測試頻率在450K-30MHz,CISPR22測試頻率在150K--30MHz,conduction可以用頻譜分析儀測試,Radiation 則必須到專門的實驗室測試。
