摘要

本文讨论了三电平逆变器中开关损耗最小化的方法。该方法采用模型预测方法对开关损耗和电压不平衡进行评估。该方法基于实现的成本函数，以提供同时最小化损耗和直流链路电压平衡控制。仿真结果表明，对于工作在16 kHz PWM频率下的3电平逆变器，与标准PWM策略相比，总损耗降低了15%。

A PWM Strategy for the Minimisation of Losses in a 3-level T-type Voltage Source Inverter

This paper discusses the approach for the witching loss minimisation in a 3-level inverter. It utilises a model predictive method which is used for evaluation of both the switching loss and voltage unbalance. The method is based on the cost functions implemented to provide simultaneous minimisation of loss and DC link voltage balance control. The simulation results shown that the total loss is reduced in 15% compared to a standard PWM strategy for a 3-level inverter operating at PWM frequency of 16 kHz.
