5 .Optional Function
5.1 Optional Function 1 : Boost Function
Wind turbine output voltage intelligent boost
The boost module starts automatically when the wind turbine voltage is lower than battery voltage , ensure that the
wind turbine normally charges the battery. The boost module shuts off automatically when the wind turbine voltage is
higher than battery voltage.
Impedance matching self-adaption
Due to internal resistance of wind turbine, battery, load, According to the impedance matching principle, The wind
Turbine will have maximum power utilization rate and maximum power output only when the input impedance equals to
output impedance, with impedance matching self-adaption .This controller enhances energy efficiency.
5.2 Optional Function 2 : Buck Function
Wind turbine output voltage intelligent buck
The buck module starts automatically when the wind turbine voltage is higher than battery voltage , The controller
real-time tracks maximum power of wind turbine and real-time limits the current of wind turbine .To solve the
problem of overheating of wind turbine.
Wind Turbine Max Current Tracking (MCT) and Max Power Point Tracking (MPPT)
When wind is in the breeze , load will slow down wind turbine rotate speed, thus reducing wind turbine output power .
