Switch-Mode Power Supplies, Second Edition

THE LATEST SPICE SIMULATION AND DESIGN TOOLS FOR CREATING STATE-OF-THE-ART SWITCHMODE POWER SUPPLIESFully updated to incorporate new SPICE features and capabilities, this practical guide explains, step by step, how to simulate, test, and improve switch-mode power supply designs. Detailed formulas with founding equations are included. Based on the author's continued research and in-depth, handson work in the field, this revised resource offers a collection of the latest SPICE solutions to the most difficult problem facing power supply designers: creating smaller, more heat-efficient power supplies in shorter design cycles.NEW to this edition: Complete analysis of rms currents for the three basic cells in CCM and DCMPWM switch at work in the small-signal analysis of the DCM boost and the QR flybackOTA-based compensatorsComplete transistor-level TL431 modelSmall-signal analysis of the borderline-operated boost PFC circuit operated in voltage or current modeAll-over power phenomena in QR or fixed-frequency discontinuous/continuous flyback convertersSmall-signal model of a QR flyback converterSmall-signal model of the active clamp forward converter operated in voltagemode controlElectronic content-design templates and examples available onlineSwitch-Mode Power Supplies: SPICE Simulations and Practical Designs, Second Edition, covers: Small-signal modeling * Feedback and ciontrol loops * Basic blocks and generic switched models * Nonisolated converters * Off-line converters * Flyback converters * Forward converters * Power factor correction
