摘要

本文提出了一种简单的方法来预测逆变器功率半导体中的损耗，其中输出正弦波是通过高频载波的脉宽调制获得的。这是通过对统计上具有代表性的人口进行大量测量的精确装置模型来实现的。并给出了计算导通和开关损耗的封闭表达式。有了这些信息和特定于应用的热环境，可以设计一个简单的电子表格，提供任何操作条件下的损耗和温度细分，包括再生、锁定转子和三次谐波失真。

A simple tool for the selection of IGBTs for motor drives and UPSs

This paper presents a simple method to predict the losses in the power semiconductors of an inverter where the output sinewave is obtained by pulse-width modulation of a high frequency carrier. This is accomplished by means of accurate device models based on a large number of measurements on a statistically representative population. Closed form expressions to calculate conduction and switching losses are also presented. With this information and the thermal environment specific to the application, a simple spreadsheet can be designed that provides a breakdown of losses and temperatures for any operating condition, including regeneration, locked rotor and third harmonic distortion.<>
