摘要
为了建立逆变器桥臂级实时仿真模型,以典型的IGBT(Insulated Gate Bipolar Transistor)与电力二极管组合作为桥臂基本结构,分析了桥臂的工作状态,重点是对暂态过程分析。在FPGA(Field Programmable Gate Array)中建立桥臂模型,并利用Model Sim软件和DA电路对该桥臂模型进行验证。验证结果表明,该模型准确、实时地反映桥臂中点输出电压、电流以及IGBT开关暂态过程中的电压、电流尖峰。
In order to build the real-time simulation model of inverter leg, this paper analyzes the working state of inverter leg basedespecially the transient state on the basic structure that composed of two pairs of IGBT and power diode combination. The bridge model isbuilt in FPGA and verified by ModelSim and DA circuit. It is accurate to reflect the module neutral-point voltage, current and peak ofvoltage and current in switching process of IGBT.
