Bypass
Description:
Defines the balancing method of the line voltages when the inverter is operating with an uneven number of
cells between phases.
Option 0 makes the inverter keep the phase voltages always balanced, with the same amplitude and with a
shift of 120°, having the phase with the smallest number of cells as the amplitude limit.
Option 1 makes the inverter keep the line voltages balanced by adjusting the angles between phases to a value
different from 120°.
