Switch-Mode Power Converters introduces an invative, highly analytical approach to symbolic, closed-form solutions for switched-mode power converter circuits. This is a highly relevant topic to power electronics students and professionals who are involved in the design and analysis of electrical power converters. The author uses extensive equations to explain how solid-state switches convert electrical voltages from one level to ather, so that electronic devices (e.g., audio speakers, CD players, DVD players, etc.) can use different voltages more effectively to perform their various functions. Most existing comparable books published as recently as 2002 do t discuss closed-loop operations, r do they provide either DC closed-loop regulation equations or AC loop gain (stability) formulae. The author Wu, a leading engineer at Lockheed Martin, fills this gap and provides among the first descriptions of how error amplifiers are designed in conjunction with closed-loop bandwidth selection. BENEFIT TO THE READER: Readers will gain a mathematically rigorous introduction to numerous, closed-form solutions that are readily applicable to the design and development of various switch-mode power converters.
Keng Wu is currently a Lead Member of the engineering staff at Lockheed Martin, Maritime Systems & Sensors, where he is responsible for various innovations in high reliability analog and digital circuit design in power electronics & systems for satellites and radar. He is highly experienced in analytical circuit design, system modeling, large-scale system dynamic study, test and integration for power electronics. His hardware design experience includes momentum wheel speed regulation, spacecraft attitude torquers, solar array step motor drivers, switching power converters in voltage-mode and current-mode control, resonant DC-DC power converters, synthetic 3-phase AC induction motor drives (Hubble space telescope), power-factor-corrected high power supplies, full and partial linear shunt, sequential linear shunt, sequential pulse width modulated shunt, limit cycle switching shunt, and battery dischargers for spacecraft. He was the lead engineer for the LANDSAT-7 (NOAA, US government) solar array shunt regulator. He oversaw electrical design, system interface, mechanical layout, design review, documentation, and presentation.
