Demonstrations of Multisim-to-FPGA Automatic Real-Time Power Converter and Power Network Simulator, Next Gen Digital Power Stack, 100 kVA Induction Motor Control and Mini-Scale Converter Prototyping System

Below you will find information on the following demonstrations:

  • Multisim-to-FPGA Automatic Real-Time Power Converter Circuit and Power Network HIL Simulator (Alpha Prototype)

At NI, we've been working for many years to develop a next generation real-time simulation platform to enable automated validation and verification of power converter control systems and other grid-tied control systems. We are proud to demonstrate at the APEC 2014 conference a first of it's kind, patent pending new technology that can automatically convert Multisim power electronics and power transmission/distribution models to a MHz speed, floating point, real-time simulation. There is no FPGA programming required and changes to the circuit diagram or component values can be downloaded in seconds. Applications for the alpha testing program are now being accepted. Read the white paper.

Below is a demonstrationof a new forward-flyback converter real-time simulation with high switching frequency:

  • Next Generation PowerStack with Serial Interface to NI GPIC

This week at the APEC 2014 conference, AgileSwitch presented their next generation SmartPower Stack with Serial Interface to the NI General Purpose Inverter Controller (GPIC). The new AgileStack(TM) marks a major step towards improving design time and system reliability, with patent pending ability to digitally monitor and handle more than 40 fault conditions, perform black box fault logging, and simplify system setup, commissioning, cabling and signal integrity.

  • 100 kVA Methode SmartPower Stack Control of a 3-Phase Induction Motor

See a live demonstation of new NI GPIC reference design example code for 3-phase induction motor voltage-over-frequency (V/f) control running on a 100 kVA Methode SmartPower Stack. The NI General Purpose Inverter Controller (GPIC) is a power conversion equipment control system carefully designed to meet the OEM price and performance requirements for most high volume switched mode power supply (SMPS) applications greater than 50 kW. See a live demonstration of the full suite of graphical FPGA/DSP programming tools with fully integrated co-simulation tools and remote web based inverter monitoring.

  • Mini-Scale Power Converter Rapid Prototyping (RCP) System and Training Kit

The GPIC mini-scale power converter rapid prototyping (RCP) system and training kit is an open source mini-scale replica of two full scale 3-phase intelligent power modules (Methode SmartPower Stack, Semikron SKiiP3) that can be operated independently or connected in a back-to-back active-front-end configuration. The control software running on the mini-scale system is identical to the software that controls a full scale SmartPower Stack. (The only difference is that different values for the analog input offsets, scaling, and fault limits are retrieved from the FPGA RAM.) NI GPIC control software reference designs are available for 3-phase induction motor control, grid synchronized 3-phase inverter control, induction motor direct torque control, field oriented (dq transform) reactive power control, and more.  We are showing the 3-phase induction motor control reference design example code running with MotorSolver 3-phase induction motor. Download the training kit instruction manual. The mini-scale back-to-back inverter kits can now be ordered in low quantity from Bloomy Energy.

Can you please provide some detailed information on the powerstacks and how I could possible acquire one? I am looking to purchase a turnkey 3-phase AC-DC Inverter in the range of 30-50kW that directly connects to the GPIC. Do you know of such inverters that are readily available?

Yes,Methode electronics manufactures the SmartPower stack and it is fully capable of operating with the GPIC.

Information is available on the Methode website at:

Please contact me at mstibgen@methode.com and I will assist you in getting pricing and delivery.

Thanks,

Mike Stibgen
