Build a DSP/FPGA platform for your own control algorithm. In one day.

As power converters and motor drives get more complex with faster switching speeds, a high performance digital control development system is required. PSIM combined with the PE-Expert4 development system provides a dedicated tool for each aspect of this workflow.

This video explains how digital control code can be generated from PSIM to run on the PE-Expert4, a high performance DSP/FPGA development system. The PE-Expert4 can be used to control hardware, a motor drive in this video, or interfaced with the Typhoon-HIL for a high fidelity realtime hardware simulation. The power stage that the Typhoon-HIL is emulating can also be exported from PSIM for a seamless integration of all three parts. The PSIM to PE-Expert4 code generation allows for up to 144 PWMs to be controlled at 400kHz. It is best practice to ensure that the control system works before the real-hardware is energized. A high fidelity Typhoon-HIL can provide the realtime verification required and allow you to energize the real hardware with confidence.

The PE-Expert4 helps with:

1) Time and Cost

The platform consists of inverter, controller, control software C library, runtime debugger and monitor, and integrated Power analyzer. Time and budget can be saved by utilizing this “all-in-one” package as a universal platform. At the same time, the user friendly interface will save users’ time through its operation and maintenance.

2) Visibility and Controllability

Novel and/or complex systems may require many points of measurement such as various sensor inputs, control program variables, and calculated values (power analysis). All these values can be observed by the system’s real time viewer, PE-ViewX and PE-Meter, without interfering in its operation. Also users can read and write any global variable in the control C program in run time.

3) Scalability and Robustness

A user can program their own FPGA design in the system in addition to DSP C source code. The system has great scalability supporting over 100 gate control and ADC (Analog to Digital Conversion) interface. For safety and robustness, dead time gate block and various interlock functions are prepared in hardware and software. This architecture is based on 20 over years experience in the industry.

If you are in multi-level converter or MMC related research for high-power applications, this system is able to generate up to 144 PWM outputs which will be ideally suited for such applications.

PE-Expert4 is a digital platform dedicated for advanced Power Electronics applications, including scalable architecture on the latest digital technology. It supports over 100 gate control and sensor inputs, and comes with a visualized software development bench for easy C programming.
