本文提出了一种预测逆变器功率半导体损耗的简单方法，其中输出正弦波是通过高频载波的脉宽调制获得的。这是通过基于对具有统计代表性的人群的大量测量的精确设备模型来实现的。还提供了计算传导损耗和开关损耗的封闭式表达式。利用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目，包括再生、锁定转子和三次谐波失真。>
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.>
