Abstract
A device to prevent reverse current flow includes a diode connected between a power supply and a load. A switching device, connected in parallel with the diode, has a power loss that is smaller than that of the diode. A low-loss current detector, arranged to turn the switching device on and off, includes a DC current detector and a comparator. The comparator compares the detected DC current value with a threshold value for an operating current and generates an output signal that determines when the switching device should be turned on or off.
