A key issue in the design of such an inverter is to determine the switching angles so as to produce the fundamental voltage and not to generate specific lower order harmonics.
在研制这种多电平逆变器时，一个关键的问题就是如何来产生开关角度，并以此来生成基波电压且不产生特定的低次谐波。
So far, we have discussed considerations specific to voltage, current, resistance, and charge measurements.
至此，我们已经讨论了专门针对电压、电流、电阻和电荷测量所要考虑的问题。
