Abstract: This study proposes a solution based on DSP technology to control the current convertor on grid side and rotor side for wind power generation and realized the hardware and software design and debug of the system.This control board consists of main board which based on chip TMS320F28335 and AD board. The software was programmed with C language. This control board could accomplish the sampling, processing, output, PWM control, at the same time, it was applied in 2MW wind power generation control. It is showed both in experiment and application that this control board reaches the requirement of precision, stability and quick response.
