I have worked as developer embedded system with microcontroller such as DSP, FPGA/CPLD, PIC, PLC and so on.
In there years, I have experiences about electronics engineering, power converter, communication such as SCI, SPI, CAN, GPIB(Agilent equipment), GPRS(Sim800, Sim808, etc).
Also I have experiences about Automatic control such as Motor Control, PI control, 2P2Z control, Hysteresis control, and so on.
I have made many equipments.
My made equipments are as follows:
- Three phase PWM rectifier(three level, two level, three phase four wires, 10kW and larger)
- UPS(parallel control)
- CVCF(High Voltage, High Current)
- VVVF(using motor control, FOC, DTC)
- High voltage DC-DC converter(High frequency higher than100kHz)
- rector heater( low frequency, medium frequency, high frequency)
- Capacitor monitor and tester combine with computer using SCI, GPIB communication.
- Capacitor cells temperature monitor using GPRS communication with SIM808(web site develop)
- wireless charger
- Welding.
