Many different usual and unusual switch-mode power supply topologies are introduced, and their specific characteristics are discussed. This includes tips and tricks on reducing EMI, expected conversion efficiencies, and other considerations when selecting and designing one of the many different topologies.

Effective filtering in DC/DC converters is crucial for reducing electromagnetic interference (EMI) and ensuring stable operation. By identifying noise paths and coupling mechanisms, designers can implement strategies to minimize noise generation and propagation. Simulation tools like REDEXPERT play a vital role in predicting noise behaviour and validating filter designs. REDEXPERT provides a user-friendly interface for selecting and optimising filter components. By carefully designing input and output filters and selecting appropriate inductors and capacitors, engineers can achieve regulatory compliance and enhance converter performance.

This session will introduce new features in LTspice26. Examples of loop stability simulation with LTspice® and LTpowerCAD® are shown.

Choosing the right inductors and capacitors is essential for optimizing the performance and reliability of SMPS designs. Power inductor selection involves understanding key parameters such as rated current, saturation current, and DC resistance. Accurate modeling of inductors helps in predicting their behavior under various operating conditions. Similarly, selecting capacitors requires consideration of factors like capacitance value, voltage rating, and aging effects. Using tools like REDEXPERT, designers can make informed choices, balancing performance, cost, and reliability. Smart component selection enhances the efficiency, stability, and longevity of the power supply.

Printed circuit board layout is a critical component of a power supply. Various important rules for generating a good board layout will be discussed. These include grounding, magnetic self-shielding, noise coupling mechanisms, and many more.
