Power Converter with Digital Filter Feedback ControlKeng Wu

In the process of designing a power supply based on the traditional analog feedback, many practitioners often resort to trial and error playing with resistive and capacitive components to make a control loop work. The procedure for the transition of power processor design from the analog domain to the digital one involves not merely hardware but also highly mathematical procedures.

Power Supply with Digital Feedback and Control presents a logical sequence leading to the identification, extraction, formulation, conversion, and implementation for the control function needed in electrical power equipment systems.

This book builds a bridge for moving a power converter with conventional analog feedback to one with modern digital filter control and enlists the state space averaging technique to identify the core control function in analytical, close form in s-domain (Laplace).

A useful reference for all professionals and electrical engineers engaged in electrical power equipment/systems design, integration, and management.

• Offers logical sequences to identification, extraction, formulation, conversion, and implementation for the control function needed• Step-by-step instructions to take an existing analog designed power processor and move it to digital realm• Presents ways to extract gain functions for many power converters’ power processing stages and their supporting circuitry

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.
