PE-Expert4 System
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.
We also offer pre-built PE-Inverter Systems to get your development projects started as quickly as it gets.
Features and Benefits
- Configurable in 6 PWM, 24 PWM, or up to 144 PWM configurations
- Up to 400KHz switching speed
- 1.25 GHz central DSP for ultra-fast control execution
- Control & measurement integrated into one hardware/software platform
- Easily monitor code execution with high bandwidth, 100KHz, real-time data link
- Runtime parameter editing
- Easy C programming interface for FPGA daughter card control code
- Data logger
1) Time and Money Savings
Save development time and stretch your budget further by utilizing this “all-in-one” package as a universal platform. The system consists of an inverter, controller, control software C library, runtime debugger and monitor, and integrated Power analyzer. Get it up and running in no time due to its user-friendly interface that will also save you time on its operation and maintenance.
2) Increased Visibility and Controllability
You will not miss a beat with the system’s real-time viewer, PE-ViewX and PE-Meter. Novel and/or complex systems may require many points of measurement such as various sensor inputs, control program variables, and calculated values (power analysis). You can observe all of these values without interfering with the overall operation. You may also read and write any global variable in the control C program in run time.
3) Scalability and Robustness
Program your own FPGA design in the system in addition to the 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 decades of experience in the industry.
Control hardware, like a motor drive (as shown in this video), or interface your PE-Expert4 with the Typhoon-HIL emulator for a high fidelity real-time hardware simulation. The power stage that the HIL is emulating can also be exported from PSIM for seamless integration of all three parts. The PSIM to PE-Expert4 code generation allows for up to 144 PWMs to be controlled at 400kHz.

PE-ViewX. The debug, control, and monitor environment for control software.
PE-ViewX is the software supporting a series of programming processes, such as coding, compiling, linking, debugging, and handling design projects. The user software can be downloaded to a target such as PE-Expert4 DSP. Then simply run the program and debug.

PE-ViewX
Project Management, Program Development, and Real-Time Debugging.
Even though you may have no C programming or FPGA design experts on your team, this flexible and scalable architecture can be built very quickly. It is a “ready-to-use” platform that enables you to learn and start advanced power electronics systems with high-end digital technology.
Variables can be edited during operation for parameter change or control; a “Virtual oscilloscope”. The PE-Expert4 consists of dual-core DSP. One core is assigned for user programming and the other is for debugging.
PEOS
PEOS is the easiest way for you to translate your algorithm into C source code in most of your power electronics applications.
For efficient or advanced experiments, C language programming is preferable since the programmer has full control and visibility for gate control, observed input value (ex. Voltage or current) for feedback control and computation, and communication. More abstract or higher-level language may not provide this level of freedom or precision.
PEOS is the solution.
PEOS consists of over 150 functions covering almost all required tasks in major power electronics design. Programmers can pick and put those functions in template form based on the required algorithm and obtain extremely effective automated programming.
PEOS function examples include:
- Triangle wave modulation command value setting for 3-phase PWM generator
- PID function initialization
- Acquiring AD converter value and encoder count
- CAN communication interface initialization
- and more!
