How to Design and Simulate a Brushed DC Motor H-Bridge Circuit Using NI Multisim and LabVIEW
Overview
With NI Multisim 12.0, you can implement the desktop simulation of your entire analog and digital system before prototyping. Digital FPGA controller logic and closed-loop simulation of transistor-level power electronics components are now possible using the Multisim/LabVIEW cosimulation feature. This tutorial shows how you can use Multisim and LabVIEW 2011 to develop the analog circuit design and digital control blocks of a brushed DC motor H-bridge circuit. In this article, learn how to use the electromechanical, power electronics, and sensor feedback blocks (new in
Multisim 12.0) to create a closed-loop control system. LabVIEW FPGA IP core development and debugging are briefly described as well. Cosimulation enables codesign of an entire system to ensure algorithms and code simulated for the FPGA in LabVIEW are verified for performance with analog circuitry and can be directly implemented in hardware with minimal changes. With the improved Multisim design approach powered by simulation, you can obtain a more accurate understanding of performance earlier in the design flow. The result of this is a reduction in prototype iterations (up to three saved PCB turns) and accurate embedded code with fewer compiles (saving as much as four hours per compile).
