摘要
设计风力发电系统变流器时,器件的损耗、冷却和最高工作温度决定了变流器设计的物理极限。当功率器件工作在设定的安全工作区时,导通损耗和开关损耗主导了器件总的损耗。本文对不同形式开关器件的损耗进行了理论分析和仿真计算,从器件本身损耗的角度,论述了在变流器功率器件的设计中选择不同形式功率器件的基本原则,为变流器功率器件的选择和损耗分析提供必要的参考依据。
When designing a wind power system converter,the loss,cooling,and maximum operating temperature of the device determine the physical limits of the converter design.When the power device is operating in a set safe operating area,conduction losses and switching losses dominate the total loss of the device.In this paper,the theoretical analysis and simulation calculations of the losses of different types of switching devices are carried out.From the perspective of the loss of the device itself,the basic principle of selecting different power devices is described in the design of the power device of the converter,which is the power of the converter.Device selection and loss analysis provide the necessary reference.
