Apparatus for driving and controlling converters and switching element modules in a wind power generation system

An apparatus for controlling converters in a wind power generation system, comprising:

• a converter driver configured to drive a converter having a smallest accumulated operation time or to drive a converter having a next sequence based on a set operation sequence of a plurality of converters when one of the plurality of converters coupled in parallel between a generator and a grid is to start being driven.

An apparatus for driving switching element modules in a wind power generation system, comprising:

• a switching element module controller configured to drive a plurality of switching element modules included in a converter coupled between a generator and a grid and which are coupled in parallel, wherein the switching element module controller is configured to sequentially drive the switching element modules one by one when an output power of the converter increases and sequentially stop operations of the switching element modules one by one when the output power of the converter decreases.

An apparatus for controlling switching element modules in a wind power generation system, comprising:

• a switching element module driver configured to turn on and off a plurality of switching element modules included in a converter coupled between a generator and a grid and which are coupled in parallel, wherein the switching element module driver is configured to drive the plurality of switching element modules so that the switching element modules have a phase difference.
