1、IGBT 耗散功率计算不管是正常负荷还是超负荷，IGBT 安全工作必须确保结温不超过。一 关于 IGBT 及损耗IGBT 模块由 IGBT 本部和续流二极管FWD 组成，各自发生的损耗的合计为 IGBT 模块整体损耗；同时，IGBT 的损耗又分为通态（稳态）损耗和交换（开关）损耗。通态损耗可通过稳态输出特性计算；交换损耗可通过交换损耗-集电极电流特性来计算。二IGBT（本部）耗散功率计算1、通态功耗的计算IGBT 通态平均功耗是。通态损耗近似是PWM 应用时，近似通态损耗。2、开关损耗计算开关损耗精确计算：测量开关过程中的波形，对其进行积分（积分时间是开通时间或关断时间）开通损耗：关断损耗：t

2、 的积分面积是以焦耳为单位的开关能量。总的开关损耗是开通与关断过程所损耗能量之和，平均开关损耗是单位脉冲开关损耗与开关频率相乘后得到：实际上和可由交换损耗-集电极电流特性曲线来估算大多数 IGBT 都会提供交换损耗与集电极电流特性曲线，如下图：文档编码:CJ2E4G2E8Z7 HE9N3K8I8D4 ZH2D4N10K5F8文档编码:CJ2E4G2E8Z7 HE9N3K8I8D4 ZH2D4N10K5F8文档编码:CJ2E4G2E8Z7 HE9N3K8I8D4 ZH2D4N10K5F8文档编码:CJ2E4G2E8Z7 HE9N3K8I8D4 ZH2D4N10K5F8文档编码:CJ2E4G2E8
