"Power Supply Design Using LTspice"

 

 

 

 

 

 

 

 

 

 

 

 

 

 

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-day webinar, we're 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.

 

Students will have their own copies of the simulation files to run during the class, and the instructor will be answering questions on the spot throughout.

Date: January 26-27, 2018 (Friday, Saturday)

 

Time: 8AM - 2PM PST

Location: Online (With LIVE instructor)

This is a companion webinar to the “Power Supply Design Using LTspice.” This webinar can also be taken as a stand-alone course on PCB design.

In this course we will take you through the entire process of PCB Design. We will start with a high level overview of the steps and software necessary to turn a circuit design into a PCB prototype. Then we will dive in as we demonstrate how a power supply design, from the companion webinar, is rendered in schematic capture and turned into a PCB layout. Along the way we will cover creating components, managing component libraries, laying copper tracks and copper pours, using vias to make connections across layers, as well as adding silkscreen and multi-layer boards.

In the second half of this workshop we will cover UL creepage and clearance requirements, minimizing EMI from the switching frequency of a switch mode power supply, and managing heat from the power components. Then we will look at Designing for Manufacturing and Design Rule Check. We will also add a layer for Assembly Drawings and export a 3D model of the board to specify the mechanical aspects of the PCB. Finally, we will generate all of the output files including Gerber files for PCB manufactures, Bill of Materials for sourcing components, XY Component Positions for populating the PCB. We will also review the files in a Gerber viewer and look at the prototype ordering process.

We will be using DesignSpark PCB Layout software, which is a powerful free software with no limitations from RS Components. We will also be using Viewmate Deluxe from Pentalogix. You may use their free version to follow along in the course.
