Digital Control System with user
friendly C programing bench

Building DSP/FPGA platform for your own control algorithm
within a day!

Power electronics consists of variety of elements such as electric circuit with power device, digital control, microprocessor, embedded software and so on. When researchers or engineers bring up a bench for advanced system, such as motor drive with advanced control algorithm or MMC (Multi Module Converter) with many gate controls, normally they face three challenges, 1) time and cost 2) visibility and controllability, and 3) scalability and robustness. Introducing Myway Plus Corporation PE-Expert4 series, the universal digital platform solution, brings perfect solution for those challenges.

1) Time and CostPlatform consists of inverter, controller, control software C l ibrary, runtime debugger and monitor, and integrated Power analyzer. Time and budget can be saved by utilizing this "all-in-one" package as universal platform. At the same time, super user friendly interface will save users' time through its operation and maintenance.

2) Visibility and ControllabilityNovel and/or complexed system 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 real time viewer, PE-ViewX and PE-Meter without interfering operation. Besides user can read and write any global variable in your control C program in run time.

3) Scalability and RobustnessUser 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.

PE-Expert4, the digital control system

Hardware feature

200kHz carrier vector control

TI 1.25GHz dual core DSP (TMS320C6657) enables high speed vector control. Normal vector control including PWM command value output can be performed within less than 5μs.

Runtime parameter editing (Carrier Frequency)

Without interfering control program operation, any parameter can be modified safely. In the following example, carrier frequency is modified during operation.
