4.2.1. Feeding and regenerative operation
The digitally controlled TC.GSS power supply is a bidirectional electrical
power supply that provides two operating modes in the four quadrant
field. Feeding and regenerative operation.
Feeding operation (Q1):
Feeding operation is achieved via positive set values for DC current and
positive DC voltage.
The energy flows from the electrical supply system to the item under
test (load).
Regenerative operation (Q4):
Regenerative operation is achieved via a negative set value for the DC
current and a positive set value for the DC voltage. Due to the negative
current the power is also negative.
The energy flows from the item under test (load) to the electrical supply
system.
Multi-unit system operation
If several TC.GSS power supplies are utilised in a multi-unit system, the
overall system is controlled by a master device. Multi-unit operation is
possible for Q1 and Q4 operation.
