Abstract

When integrating multiple sources to supply power to a single load, it is necessary to ensure that excess power available from a single source does not flow into the other sources. This is commonly done with OR diodes placed for each source being used. Despite its simplicity, this protection method suffers apparent efficiency loss through the diodes, especially when large current is involved. This paper discusses other and less intuitive consequences of using OR Diodes including distortion, system versatility, and cost in component sizing. Results of our study show that these consequences are largely resultant of unequal power sharing between the sources to power the load and are more prominent as the difference in presented input voltages increases.
