High-Quality Wind Turbine On-grid Converter | China Suppliers & Factory with Advanced Power Technology

The Convertor is a vital component in wind generator systems, engineered for compatibility with both permanent magnet synchronous generators and asynchronous generators. It efficiently converts the variable AC current generated by wind turbines into stable DC current, and subsequently into consistent AC current, ensuring stable frequency and voltage control across various wind speeds. This cutting-edge technology minimizes any impact on the grid, offering superior fault ride-through capacity and remarkable adaptability to grid conditions, Our small wind turbine grid-connected system includes key elements such as the wind turbine, rectifier, electronic dump load, and grid-connected inverter. The wind energy harnessed by the turbines transforms into alternating current with fluctuating amplitude and frequency. This variable AC current is processed by the controller to produce DC current, which is then converted back into a synchronized sine wave current by the grid-connected inverter. This inverter serves as the heart of the wind turbine grid-connected system, Utilizing a state-of-the-art 32-bit DSP chip control from U.S.-based TI and advanced IGBT intelligent power modules from Japan, our system integrates active current-controlled PWM inverter technology. This not only enhances the reliability of the power supply but also includes protection functions, ensuring a high power factor and pollution-free harmonic power supply. As a leading manufacturer in China, we pride ourselves on being a top supplier and factory of innovative wind energy solutions
