PROBLEM TO BE SOLVED: To provide a back-flow prevention support device for setting functions or behaviors of an element or a circuit that performs backflow prevention of a feed passage of direct current power, capable of avoiding unnecessary power loss or voltage drop without significantly complicating a configuration.SOLUTION: The back-flow prevention support device includes: polarity discrimination means for discriminating whether polarity of a direct current power is correct; and control means for forming an element to prevent back-flow of a feed passage of the direct current power or a bypass circuit. |
