Switch Mode Power Supply Design (AC13-6-0)

SynopsisUnlike 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. 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 therefore provides such knowledge, with examples of how the theories are applied in practical circuit.

Course Highlight
Participants will learn

• A sound understanding of the operating principles of switch mode power supplies
• The differences and choices between the different SMPS topologies
• Practical issues related to implementation of SMPS as well as key areas for more advanced and recent development in SMPS
• Tried-and-proven techniques that enable the engineer to always come up with robust designs for their power supply products

Switch 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.
