LT Spice & The AC Line

Synopsis 

AC to DC converters are everywhere…they charge our phones, run our computers, power our LED lights and run our washing machines. But the AC line is a hostile environment, and converters powered from it must be specially designed if they are to survive. Not only is the AC line high voltage---120VAC and 277VAC in the US, and 230VAC everywhere else---but there are brownouts, surges, dropouts, and, most dreaded of all, lightning strikes that take a variety of forms.

In this webinar, we’ll be looking at modeling the AC line and its disruptions using LTspice, and looking at circuitry that can be used to ensure your power supply’s survival in the environment. This course is suitable for power supply engineers of all levels of experience who need their converters to interface with the AC line.

Modeling Discrete Components in LTspice

Synopsis 

Engineers use discrete components all the time. Resistors, capacitors, inductors, diodes and transistors, just to name the most common ones. But a capacitor you buy isn’t just an ideal component like you learn about in school. It has ESR. It has ESL. It has a maximum voltage rating, and a maximum ripple current. And there are ten different kinds of capacitors. How do you select one that fits the needs of your design without violating any specs? 

 

In this course, we will be looking at some of the details of the various discrete components and how to build adequate models of them in LTspice. If you aren’t sure of the difference between a ceramic capacitor and an aluminum; if you aren’t sure about how much voltage can be safely handled by an 0805 resistor; if you aren’t clear about the RMS current rating of an inductor vs. its peak current rating; if you aren’t immediately clear on the answer to all of these questions, this course is for you!

 

This is an introductory course suitable for power supply engineers---and for any Electronic engineers---who need to know more details about what exactly the components in their design are doing. After this workshop you will know when *not* to use electrolytic capacitors, when *not* to use 0603 resistors, and much more.

Design of Inductors and Transformers

Synopsis 

Designing magnetics is the single most challenging aspect of the design of a power supply. Reference materials are hard to come by and tend to leave out a lot of practical information necessary to design your own, or even to be able to check that your vendor has done a good job of designing it for you. In this workshop we will help you through this process by focusing on practical aspects of the design of inductors and transformers.

 

This course is suitable for power supply engineers of all levels of experience who need to design power supplies that need isolation, that operate at >100W or both.

LTspice and Control Loops

Synopsis 

Control loop design for power supplies can be challenging, even for those with a background in analog electronics. Translating from textbook theory to actual designs that can be implemented on a circuit board requires experience that can take years to acquire.

In this class we will speed up the process by focusing on practical aspects of simulating and designing control loops for power supplies. In particular, we will be using LTspice, a free simulator, to compute the necessary feedback system and then verify its design. We start from the basics, explaining practically how to measure the transfer function of the power stage of a power supply.

We show how to build a switching model of a power supply in LTspice. We show how to use the latter to measure the transfer function. We then look at the three main types of feedback control, and build models of these. We combine the two models together and show how to measure the complete transfer function of the power supply, how to verify its bandwidth and its phase margin. Finally, we verify its stable performance.

 

This course is suitable for power supply engineers of all levels of experience who need to design power supplies that are stable and perform well under step loads.

MTTF (Failure Rate) Calculation Using Excel

Synopsis 

You’ve designed a power supply, but is it going to last long enough in the field, or are you going to be getting returns from irate customers? Calculation of failure rate of a power supply is key to ensuring the length of service or your design.

In this course, we will be looking at the meaning of MTTF, mean-time-to-failure and how it differs from MTBF. What are the components that usually contribute to short MTTF, and how can they be avoided? What temperature should be assumed? We’ll be using an Excel spreadsheet to see how MTTF can be calculated. And we’ll be looking to see what you can do if your design doesn’t meet requirements.

This course is suitable for power supply engineers of all levels of experience who need to design power supplies with a specified minimum life-time.

Power Supply Design Using LTspice

Synopsis 

Designing a power supply from scratch can be an arduous task, involving a wide variety of different kinds of knowledge. Engineers have to be familiar with topologies, component selection, safety and governmental regulations and magnetics design, just to name a few. And you need to make sure that when the PCB is fabbed that the design is going to work the first time. How can you accomplish all this with a limited amount of time?

In this two-part webinar, we are going to teach you how to go from specification to successful design in a short amount of time. The key ingredient is going to be the extensive use of simulation, from estimating losses in MOSFETs and diodes, to verifying control loop stability and bandwidth, and to checking the parameters of magnetics design. We’ll be taking an actual design from component selection through to the point where it’s ready to go to layout, using LTspice, a free simulator, to verify each step of the design.

Part 1: Specification writing; Topology Selection; IC Selection; Component Design; Overview and Cautions of Modeling

Part 2: Magnetics Design; State-Space Average Model; Control Loop; Switching Model; Load Step Modeling; EMI Modeling

This course is suitable for power supply engineers of all levels of experience who need to shorten their design cycle time and ensure that fewer board spins are necessary.

LTspice and LED Systems

Worst-Case Analysis - A How-To Guide

Synopsis 

You’ve just designed a power supply or an analog system that meets specs, and now you’re ready for production. But how do you know what happens when that resistor is at the lower end of the manufacturer’s tolerance? What happens to the electrolytic capacitor’s capacitance when it gets hot? And what if the next lot of opamps’ leakage current is at maximum spec rather than the nominal on your test bench?

 

This course looks at analyzing the worst-case performance of your design. It shows you a systematic method for telling if there is going to be significant rejection on the production line. It shows you some significant issues with Monte Carlo analysis. And it tells you when it’s appropriate to use true Extreme Value Analysis instead.

This course is suitable for power supply engineers of all levels of experience who need to evaluate whether their design is suitable for high-volume production, as well as for those working in industries where ‘failure is not an option’.

Synopsis 

The design of LED systems can be challenging, even for those with a background in power design. Such systems have a complicated mixture of electrical, thermal and optical characteristics, all of which interact. In this class we will focus on modeling of actual LED systems using LTspice. We start from the basics, modeling LED characteristics and understanding their datasheets. We then look at some of the choices for driving LEDs, whether from DC source or from the AC line. Some of the switch-mode power supply options are examined in more detail. We then put the LEDs together with the power supply to see how they interact, and build interacting electrical/thermal/optical LTspice models of the whole system.

This course is suitable for power supply engineers of all levels of experience who need to design LED power supplies and LED systems that perform both electrically and thermally.
