When the master LGM reaches 45 kW, the second
LGM is selected. For stability reasons, each LGM
that has just been selected in the cascade switches
to the minimum rate before being freed at modula-
tion.
The first LGM then progressively decreases its
power while the second LGM increases its power
until they have reached the same power level. From
then on the two LGMs modulate together at the
same power level.

When both LGMs each reach 18 kW, the slave LGM
is deselected. The master LGM then compensates
the loss by increasing its power (switching from
18 kW to 36 kW). The master LGM then modulates
alone.
