| Abstract: | According to the needs of distributed grid-connected wind power generation systems,the converter which can operate under grid-connected condition was designed.The converter use ZVS-PWM technique and the average current mode control method,and the use of maximum current flow to achieve automatic multi-parallel current.The experimental results show that the converter can significantly reduce the cost of wind power conversion process,with stable output current and not forming a sharp shock,which prove the corr... |
