Control System Design for Switch Mode Power Supply (AC72-6-0)

SynopsisSwitch Mode Power Supply (SMPS) utilizes solid state switching devices operating in high frequency digital mode to deliver well-regulated DC outputs that are essential to drive a wide variety of today’s electronics equipment and systems. Unlike other technologies which usually require knowledge in only one key area, SMPS encompasses a wide range of knowledge in areas that include power engineering, high frequency electronics design, control loop design, understanding of component and device characteristics, EMI and PCB layout. As an essential part of all electronic equipment and systems, it is important that engineers and technicians whose work involve the design, production and integration of SPMS into other systems to have a sound knowledge on the working principles and various aspects of a SMPS.

This course covers the various aspects of the control loop operation and design specifically targeting the SMPS. An overview of control loop operation is first presented. Relevant aspects of control loop operations and design related to SMPS are then discussed. Control loop circuits operation and implementations are described. System models of the various SMPS topologies are introduced, followed by the various compensator designs for the different types of system.
