Rectifier and Dump Load Controller

online order

Rectifier: to rectify variable frequency AC output of wind generator into steady DC.

In grid-tied system, it transfers the power from wind generator to steady DC power. When the output voltage reaches the required DC voltage of grid-tied inverter, the inverter will connect to the public grid and feed into the grid.

When the output voltage is too high, the extra power will be consumed by the metal dump load, which is connected to the controller automatically to achieve unloading function.
