The DSP-mount system is expandable. Simply choose a board to match the experiment, and control the system with the Integrated Development Environment, PE-ViewX.
Basic system: MWPE4-RACK12, MWPE4-C6657, MWPE-VIEW-X, MWPE-EXP4-LIB.
Power electronics consists of a variety of elements such as electric circuit with power device, digital control, microprocessor, embedded software, etc.
When engineers discuss a bench for advanced systems, 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 the PE-Expert4 series, a universal digital platform solution that delivers the perfect solution for those challenges.
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.
