IEEE Webcast on Power Converter Controllers Design for Smart Grid

Register now for TOMORROW's IEEE Webcast on power converter controllers design for smart grid with NI LabVIEW FPGA and Multisim Co-simulation tools.

Register HERE

Abstract:

"Just say no to trial and error when designing your next smart grid power converter or flexible AC transmission control system. Learn how to fool proof your design cycle by applying appropriate validation and control synthesis techniques. New methods will be demonstrated through the design of two FPGA-based control systems: 1. A classic field-oriented control and space-vector PWM inverter and 2. The application of set-theoretic methods in power converter controller synthesis to optimize the reliability of the closed-loop system while protecting component lifetime.  Join us for demo based introductions to the proposed techniques, including: •     New developments in set theory to automatically synthesize low complexity control laws with strong reliability guarantees, •     Power electronics co-simulation tools for automated testing of FPGA control software, •     Real-time simulators and miniature-scale grids for rapid prototyping and hardware-in-the-loop verification, and •     Deployment-ready inverter stacks and FPGA control boards for high volume commercialization."

LabVIEW Instruments for Different Versions of Multisim

Hello Circuit Designers,

I wanted to bring your attention to recent update!

To be able to run a LabVIEW instrument in Multisim the LabVIEW Run-time Engine (RTE) version of the instrument must be installed on your computer.

We now have different versions of the instruments uploaded to the community page.

With Multisim 12.0.1 released on September the 14th of 2012, you get the RTE2012 automatically installed and can run all the updated versions of the instruments and analyses in Multisim.

If you are a Multisim 12.0 user you only have the RTE2010 and RTE2011 installed and will have to install the 2012 one manually.

We will always keep all the instruments up-to-date and available for download.

Please let me know your feedback and if you have any questions about installing a custom LabVIEW instrument for Multisim.

Calculate your Circuit Simulation Rate

Have you ever wondered how long it would take you perform a few milli-seconds transient analysis of your circuit?!

Here is an analysis tool developed in LabVIEW that ties into Multisim simulation environment and could tell you exactly at what rate your simulation is running.

Multisim 11 and 12.0 download

Multisim 12.0.1 download

Enjoy!

Multisim PXI Instruments

Hello Circuit Designers,

I would like to tell about a new excellent set of virtual instruments available for use in Multisim. Now you can add 5 new measurement instruments that can both measure simulated data and real prototype data. This unique (and unparalled) functionality, provides the engineer with a major step forward in their ability to effectively simulate and validate their prototype designs using NI Multisim and PXI hardware platforms.

The 5 instruments are available for download on NI labs, and are:

    1. DC Variable Power Supply  [which can also connect to the NI PXI-4110 hardware]
    2. 100 MHz 2-Channel Scope [which can also connect to the NI PXI-5122 hardware]
    3. 100 MHz 20-Channel HSDIO [which can also connect to the NI PXI-6552 hardware]
    4. 7.5 Digit Multimeter [which can also connect to the NI PXI-4071 hardware]
    5. 200 MHz Arbitrary Waveform Generator [which can also connect to NI PXI-5422 hardware]

Enjoy!

NI ELVISmx 4.3.1

NI provides an enhanced circuits teaching solution with improved connectivity between Multisim and laboratory hardware.

NI ELVISmx 4.3.1 is the application software that supports the National Instruments Educational Laboratory Virtual Instrumentation Suite II/II+ (NI ELVIS II/II+) and the NI myDAQ. These devices use the ELVISmx LabVIEW-based software instruments to provide the functionality of a suite of common laboratory instruments.

NI ELVISmx 4.3.1 contains the NI ELVISmx Instrument Launcher, LabVIEW Express VIs and SignalExpress steps for programming the NI ELVIS II/II+ and the NI myDAQ hardware.

Here is the list of the  available NI ELVISmx instruments you can download and install:

NI ELVISmx Digital Multimeter

NI ELVISmx Digital Oscilloscope

NI ELVISmx Bode Analyzer

NI ELVISmx  Variable Power Supply

NI ELVISmx Function Generator

NI ELVISmx Arbitrary Waveform Generator

NI ELVISmx Dynamic Signal Analyzer

NI ELVISmx Digital Writer

NI ELVISmx Digital Reader

Installing a Custom Simulation Analysis in Multisim

To properly install a custom simulation analysis or instrument in Multisim (created using LabVIEW), follow the below steps:

1. Open Multisim and check the default location for the User LabVIEW instruments path under Options»Global Preferences as shown below

1.jpg

By default, this path should be: C:\Users\Public\Documents\National Instruments\Circuit Design Suite 12.0\LVInstruments

2. Download the LabVIEW .LLB and .DLL files of the analyses (check the documents section of this community) and save them under the folder specified in Multisim Global Preferences as shown below
