This paper proposes a design scheme for an LCL-filter used for the three-parallel operation of the power converters in high-capacity

wind turbines. The designs of the power devices and grid connected filter are difficult due to the high level voltages and currents in

huge-capacity wind turbines. To solve these problem, this paper presents three-parallel operation and LCL-filter design techniques

optimized by parallel operation. Furthermore, the design of an inverter side inductance of the LCL-filter is discussed in detail

considering the switching modulation method. Simulation and experimental results demonstrate the validity of the designed filter

and wind turbines.
