The 2016-17 Power Supply Design Seminar series, the 24th since its introduction in 1977, provides rich, technical and practical presentations which combine new advanced power supply concepts, basic design principles and "real-world" application examples. Whether this seminar is used to gain fresh knowledge of power supply design, or as a review for those experienced in power supply design, the topics presented will be worthwhile for all levels of expertise.
This year, we've added even more to your experience. In addition to the traditional lecture hall presentations, we will also be offering a separate room to showcase power supply hardware demonstrations. The seminars now allow you to customize your day with in-depth technical papers presented by expert power system designers, live hardware demonstrations, and personal consultations with the experts.

Power converters often take up considerable board space. Converters operating in the megahertz range enable the use of smaller passive components (inductors and capacitors). However, switching losses are prohibitively large in conventional buck converters when attempting operation in high-frequency, high-current and high-voltage-conversion-ratio (for example, 10-to-1) applications. The series capacitor buck converter topology can significantly reduce the size of point-of-load (POL) voltage regulators. This paper focuses on the limitations of conventional high-frequency buck converters and how the series capacitor buck converter overcomes these challenges.
The flyback converter is widely used in AC/DC power supplies, due to its simplicity and wide operating range. It also eliminates the output filter inductor and free-wheeling rectifier that are required for forward-mode topologies. Flyback converter performance is dominated by three main topology components – primary switch, secondary rectifier and transformer. This paper focuses on the importance of transformer design, since this single component has a profound impact on the converter efficiency and EMI performance.
Engineers have been designing switch-mode power converters for some time now, but if you are new to the design field or you don't compensate converters all the time, it will require some research to do correctly. This paper will break down the procedure into a step-by-step process that engineers can follow to compensate a power converter. The theory of compensation and why it is needed will be explained.
A bidirectional DC/DC converter is a key element of many new applications, such as automotive, server and renewable-energy systems. Low-voltage bidirectional DC/DC converters are usually nonisolated. All bidirectional converter designs or products currently on the market are based on the hard-switching synchronous buck topology. This paper uses an automotive 48-V/12-V bidirectional converter as an example with which to revisit the hard-switching synchronous buck topology and compare it to the transition-mode totem-pole zero-voltage-switching (ZVS) topology.
Emerging wide bandgap (WBG) silicon (SiC) and gallium nitride (GaN) power devices are gaining popularity in power electronics and have the potential to significantly increase a power converter's efficiency and power density. This paper examines WBG power devices in order to achieve higher performance and reduce system cost. The analysis of switching and conduction loss behavior of WBG power devices supported by experimental data is provided to ensure a robust design. Important design issues including drive technique, mitigating layout and packaging parasitics, high-frequency measurements and simulations are considered in detail.
When it comes to designing buck-boost converters, there is a huge gap between the simple inverting buck-boost converter in textbooks, which actually produce a negative output voltage, and real-world buck-boost applications that require a positive output. This paper fills a gap in buck-boost literature by presenting various topologies used in noninverting buck-boost designs.
Modular-built power supplies could bring additional value to applications in the industrial space though an increased number of possible solutions, flexibility and performance, as well as lower cost. Based on achievable power levels, in this paper I describe the selection of the main power stages, including a continuous conduction mode (CCM) power-factor-correction circuit. Also included is a peak current mode-controlled isolated direct current (DC)/DC resonant phase-shifted full-bridge converter with synchronous rectification.
This lecture-only, short course provides an entry-level introduction to isolated power supply topologies. Topologies covered include flyback, Fly-Buck™, forward, half-bridge, and full bridge. The basic operation and fundamental characteristics of each topology are described. This course is geared for engineers who have no prior experience with isolated topologies.
This presentation provides an overview of three power supply design tools available from Texas Instruments.
The audience will learn where to access each tool on ti.com and understand the basic functionality. This presentation will be valuable for power supply designers from novice to senior.
This presentation will focus on the basics of the PMBus specification and protocol, and includes how it's used to enable Adaptive Voltage Scaling (AVS) of power supplies, what commands are used, and how high-volume programming of PMBus power supplies is implemented. This lecture is geared towards engineers that want to gain an overall understanding of PMBus and its benefits to power design. It will include an Ethernet Switch PMBUs POL design demo using TI's Fusion GUI Digital Power Designer.
This lecture-only, short course provides an entry-level introduction to USB Type-C and Power Delivery. A general overview of the technology is followed by a detailed look at single-port and multi-port source-only AC/DC applications. This course is geared for engineers interested in USB charging applications.
This lecture provides a review of an AC/DC power supply reference design with universal AC input and 25V/13.5A and 12V/1A outputs. An LLC+PFC combo controller is applied for the main 25V/13.5A output, while a flyback is applied for the auxiliary 12V/1A output. This design has low no load power consumption (152mW@230VAC) and over 93% peak efficiency. This design also meets the 80PLUS Gold requirement for 115VAC internal power supplies.
In today's industrial and automotive applications, engineers strive to bring innovative approaches to creating smaller, cost-effective solutions that can tolerate higher voltages and higher temperatures while minimizing total system noise. This session focuses on how to select and design Low-EMI wide VIN DC-DC converters for industrial and automotive applications. This session will introduce key focus areas such as EMI input filter design, Spread-Spectrum, Gate-drive slew rate adjustment and PCB layout techniques to minimize EMI.
