Development of a Power Balance Regulator in Wind Driven Generator System

A kind of power balance electric regulator which is used to balance output power between generators when several wind driven generators are shuntly fed to a battery set is introduced. In the regulator a buck DC/DC converter is included. The output voltage and current double close loop feedback control stratagy is adopted. The main power MOSFET is operated at zero voltage off condition. A 3 kW and a 5 kW regulator devices with high efficiency, simple construction, lower cost and high rellabillty are successfully developed. The experimental result shows that this kind of power regulator can control the charge voltage and current of battery quickly with the protective function of input overvoltage, output overvoltage and overcurrent. It effectively solves the problems, such as instantaneous or long term overload of parrallel generators, the unbalanced output power between generators, and the overcharge of battery set. It would have active effect on developing the wind driven cause in China.
