在汽车应用中，Z源逆变器是一种单级逆变器，它提供了将直流链路电压升压到所需值的有用功能，而与电池电压无关。可调节的DC链路电压的优点可以用作电驱动的损耗最小化控制的自由度。然而，半导体在升压操作期间经历高应力。本文介绍了脉冲模式，减少升压操作过程中的电力电子损耗。
In automotive applications, the Z-source inverter is a single stage inverter that provides the useful feature of boosting the DC-link voltage to a desired value independently of the battery voltage. The advantage of an adjustable DC-link voltage can be used as a degree of freedom for a loss minimized control of electric drives. However, the semiconductors experience high stress during boost operation. This paper presents pulse patterns that reduce power electronic losses during boost operation.
