本章指出，顺序开关不仅适用于集成二极管紧密安装在散热片上的IGBT模块，还适用于完成工业标准的两电平电压源型逆变器(VSI)。因此，这些产品的功率能力和总开关频率可以通过将它们中的几个与顺序开关并联使用来提高。利用这种方法，可以以最少的设计和开发工作建立起一种新型的驱动逆变器电气测试平台。这为驱动逆变器制造商提供了一种替代方案，可以在不需要大量真实机器的情况下测试其整个产品系列。本章中提供的讨论证明，所谓的虚拟机(VM)是一种硬件在环系统，允许在真实功率水平下测试逆变器，而不需要安装和操作真实机器。该电机具有与真正的感应电机甚至同步电机相同的特性。可以通过软件模拟不同的机器及其各自的负载情况，这意味着被测试的驱动逆变器可以在其正常模式下运行(照常)。无需对逆变器或控制单元进行任何修改。
The chapter points out that sequential switching is not only applicable to IGBT modules with integrated diodes mounted closely on a heat sink, but also to complete industrial standard two‐level voltage source inverters (VSIs). Thus, the power capability and the overall switching frequency of these products can be increased by using several of them in parallel with sequential switching. Using this approach, a novel electrical test bench for drive inverters can be set up with a minimum effort on design and development. This provides an alternative for manufacturers of drive inverters to test their complete product range under real power levels without the requirement for a multitude of real machines.The discussion provided in the chapter proves that the so called virtual machine (VM) is a Hardware‐in‐the‐Loop system allowing an inverter to be tested at real power levels without the need for installing and operating real machines. The VM has the same characteristics as a real induction motor or even a synchronous motor. Different machines and their respective load conditions can be emulated by software, which means that the drive inverter under test can operate in its normal mode (as usual). No modification has to be done to the inverter or to the control unit.
