| Abstract: | In order to solve the problems existing in power quality signal generator,such as complex structure,single function and difficult achieving high power,a new kind of power quality signal generator with 2H bridge cascade structure was designed,which uses FPGA and DSP as control chip and carrier phase shift PWM control.Based on simulation with MATLAB,a three-phase power quality signal generator prototype was developed,which outputs power quality waveform including voltage swells,dropping,harmonics and flicker,etc.The experimental results show that the signal generator has characteristics such as simple structure,high power output and etc.,meets the needs in different occasions. |
