53/78 SUREWAVE SFC USER MANUAL
The input voltages are represented by vertical bars at the input and output columns, and a hori-
zontal line across the bars indicates the 100% mark (normalized to the nominal value of the volt-
age).

10.2.1.3 Column 3 – Diagram
Shows a single-line diagram indicating the present operating status of the SFC and indi-
cates the power flow path (direction of power flow is not shown). See Chapter 11 Opera-
tion of the SFC for more detail.
The power flow in the SureWave SFC system can be summarized into two main states, Running
and Stopped. The thick blue lines will indicate the energized sections.
For applications where the SFC is energized at both ends, the main difference between Running
and Stopped states is the energization of the DC bus link between the inverter and the rectifier.
