2.2.2 When the Load Generates a Reverse Current to
the Power Supply
The unit cannot absorb a reverse current from a regenerative load
such as an inverter, converter, or transformer that supplies current to a
power supply. Consequently, the output voltage will increase and the
output will fluctuate.
For these types of loads, connect a resistor R
D
as shown in Fig.2-3 to
bypass the reverse current. However, the current capacity to the load
decreases by Irp.
•
For resistor R
D
, select an appropriate resistor rated
for the power (allowing sufficient margin).
If a resistor with insufficient rated power for the circuit
is used, it may burn out.
