Output Characteristics
An ideal constant-voltage power supply would have a zero output impedance at
all frequencies. Thus, as shown in Figure 7-3 , the voltage would remain perfectly
constant in spite of any changes in output current demanded by the load.
The ideal constant-current power supply exhibits an infinite output impedance at
all frequencies. Thus as Figure 7-4 indicates, the ideal constant-current power
supply would accommodate a load resistance change by altering its output
voltage by just the amount necessary to maintain its output current at a constant
value.
The output of the E3633A and E3634A power supplies can operate in either
constant voltage (CV) mode or constant-current (CC) mode. Under certain fault
conditions, the power supply cannot operate in either CV or CC mode and
becomes unregulated.
