本文提出了一种有趣的方法，用于对驱动应用的电压源逆变器进行硬件在环测试。为此，被测逆变器没有连接到真实的机器，而是连接到第二个逆变器，其行为类似于电机。通过并联连接的标准逆变器的顺序切换来增加所谓“虚拟机”的功率能力。并联的逆变器可以是与被测逆变器相同的类型。因此，对于制造商的产品范围而言，驱动逆变器测试不存在功率限制。
This paper presents an interesting approach for hardware-in-the-loop testing of voltage source inverters for drive applications. For this purpose the inverter under test is not connected to a real machine, but to a second inverter instead, which behaves like an electrical machine. The power capability of the so-called “Virtual Machine” is increased by sequential switching of parallel connected standard inverters. The parallel connected inverters can be of the same type as the inverter under test. Hence there exists no power limit for drive inverter testing with respect to the product range of the manufacturer.
