4.1 Use as a DC Power Source

APS-1102 Programmable AC/DC Power Source 4-3

Once a diode has been connected, a load that does not consume power keeps its voltage

charged. The voltage of the load may be slightly higher due to the overshoot voltage and

should be carefully monitored.

Figure 4-1. Connection of Block Diode

b) Inductive load such as inductor

An inductive load generates a back EMF when current suddenly stops flowing, such as when

the output is turned off. A backflow diode is required to absorb the back EMF.

Connect a backflow diode in parallel with the load, as shown in Figure 4-2.
