Switch-Mode Power Supplies, Second Edition

fully updated to incorporate new spice features and capabilities, this practical guide explains, step by step, how to simulate, test, and improve switch-mode power supplydesigns. 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 DCM
• PWM switch at work in the small-signal analysis of the DCM boost and the QR flyback
• OTA-based compensators
• Complete transistor-level TL431 model
• Small-signal analysis of the borderline-operated boost PFC circuit operated in voltage or current mode
• All-over power phenomena in QR or fixed-frequency discontinuous/continuous flyback converters
• Small-signal model of a QR flyback converter
• Small-signal model of the active clamp forward converter operated in voltagemode control
• Electronic contentdesign templates and examples available online

switch-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
