A New System-Level Design Methodology and Platform for FPGA-based Power Electronics Control

View the webcast

Increasing adoption of field-programmable-gate-arrays (FPGAs) in grid-tied power converters and inverters for the smart grid is driving significant interest in improved platforms for development and commercialization. Modern FPGAs now provide orders of magnitude higher computer performance per dollar and per watt compared to single-core DSPs and microprocessors, in addition to their silicon gate level (SGL) reconfigurability and ultra-high-speed digital control performance.

In this presentation, a new platform and methodology for system level design of FPGA-based smart grid power electronics control systems is introduced and demonstrated. A new variable timestep co-simulation interface is developed to enable the high-speed, coupled dynamic interaction between FPGA and switched mode power circuit to be accurately captured. The same user defined FPGA software, programmed without requiring any knowledge of HDL languages, is then transferred to a pre-validated COTS control system for high volume deployment. The feasibility, validity and accuracy of the approach are evaluated through the design and testing of grid tied inverters and power converters. Additionally, an FPGA-based real-time hardware-in-the-loop (HIL) state-space simulator is developed which enables exhaustive validation testing of the physical power converter and control system. Also introduced for the first time is a new power electronics research and instrumentation system for experiential learning and teaching of modern FPGA-based power system design.

Power Converter Controller Design for Smart Grid Power Electronics

View the webcast

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.
