The need for improved power density is clear, but what limits designers from increasing power density today? Watch this five-part training series where we outline how to achieve higher power density by examining four critical aspects of high-power-density solutions, as well as relevant TI technologies and products supporting these specific requirements.
Topics in this training series:
From laptop adapters to power tools, any end equipment powered from the AC grid represents a complex load where the input current is not always in phase with the instantaneous line voltage. As such, the end equipment consumes both real power as well as reactive power from the grid. The ratio between real, usable power (measured in watts) and the total real-plus-reactive power is known as the power factor.
Electromagnetic interference (EMI) is an essential part of every power-supply design, but too often gets relegated to the end of the design flow, at which point its resolution can be time-consuming, costly and inefficient. This seven part video series will help dispel fears about EMI, and show how to find and fix the issues.
When you run into a problem in your power-supply design, the odds are that someone else has already solved the same problem on another design. Wouldn’t it be great if you could learn from their mistakes? This five part video series focuses on some of the most common mistakes in the design and troubleshooting of low-power AC/DC power supplies, specifically focusing on the flyback topology.
High-power bidirectional AC/DC power supplies are widely used as uninterruptible power supplies (UPS), energy storage systems (ESS) and onboard chargers (OBC) with with vehicle-to-grid (V2G) capability. Compared to the traditional approach ¡V using one unidirectional rectifier and one unidirectional inverter to achieve a bidirectional energy flow ¡V a bidirectional rectifier can provide advantages such as smaller size, higher power density and higher efficiency. This paper reviews topologies, design considerations and design challenges of high power bidirectional AC/DC power supplies.
How many times have you said, “I would like to prototype an idea with TI silicon but I can not get software resources" or “I don’t know how to prototype/program.”
This training shows you how to get started prototyping on TI solutions with minimal or no programming, including the following tasks:
This sections covers tips for selecting the appropriate capacitors for your switching power supply.
This sections covers tips for selecting the appropriate inductors for your switching power supply.
In recent years, resonant converters have become more popular and are widely applied in various applications like servers, communications and consumer electronics. The resonant converter can easily achieve high efficiency and allow high frequency operation with its intrinsic wide softswitching ranges. However, resonant converters rely on frequency modulation (FM) to achieve voltage or current regulation instead of traditional pulse width modulation (PWM).
With the development of telecommunication and mobile technologies, smart phones, tablets and notebook computers became essential parts of everyday life. Because of this, we require more powerful processors, which requires increased batter size and higher levels of AC/DC chargers, while the size is expected to remain the same or grow smaller.
This course demonstrates how an active clamp flyback converter achieves zero voltage switching (ZVS) and recycles the leakage energy of the transformer to improve efficiency in higher frequency operation. Although it is well known that switch node capacitance determines the circulating energy for ZVS, the capacitance-nonlinearity impact from each of the two primary-side switches and from the secondary synchronous rectifier has not been well understood.
The presentation addresses the design consideration of USB Type-C power delivery. USB Type-C is the new trend of Industrial, automotive and personal electronics devices. In the training, audience will be able to learn more about USB Type-C power delivery (PD) requirement and understand architecture of USB Type-C PD, AC/DC power source.
Control theory is often thought to be difficult to understand and theoretical approaches usually have lots of Mathematics and talk about Loop Gain, complex frequency, H(s), G(s) and so on.
The topics will cover system design issue and solution for Building Automation, Power Delivery and Test & Measurement. TI experts introduce the latest technology and innovation system reference design. Discover ways to enhance the time-to-market and create safer and efficient industrial systems.
The Phase Shifted Full Bridge (PSFB) has always been considered the best design for high power DC/DC conversion. However, a newer technology called Full Bridge LLC (FB-LLC) has recently been used and accepted for high power DC/DC conversion. In this 3 part series, we will go in-depth in discussing the pros and cons of both the PSFB and FB-LLC. We will then compare the basic problems between the PSFB and FB-LLC and give ideas on how to choose between the two given a certain application. Lastly, we will review some Reference Designs.
Applications Engineer Jason Tao discusses PFC basics, topology comparisons and design considerations to achieve a cost-optimized and efficient PFC design.
