| As shown in the illustration, what is the purpose of the DC link within the frequency converter? |
| A) It merely provides a conducting path between the bridge rectifier output to the controlled inverter input with no other purpose. |
| B) It is an inductor coil that smoothes out the DC current flow outputting from the bridge rectifier on the way to the controlled inverter input. |
| C) It converts the bridge rectifier AC output to the DC required for input to the controlled inverter. |
| D) It controls the gate trigger pulses to the controlled inverter, thus controlling the output frequency. |
