What are the three components of the three-phase AC variable speed drive system? Drag and drop the correct components to the diagram below.
What are the components of the drive controller? Drag and drop the correct components to the diagram below.
In a typical 3-phase frequency inverter, there are six switches. The longer a switch is on, the higher the AC output voltage. Conversely, the longer a switch is off, the lower the output voltage. This duration of ON-time for each pulse is called ___________.
