IPC: H02M3/28
Filed: 2000-09-06
Abstract: PROBLEM TO BE SOLVED: To eliminate an effect of inverse current from another power supply unit at the time of parallel operation with a simple structure. SOLUTION: In parallel operation, for example, when a rectifying switching element 6 of a power supply unit body 9a is ON, the inverse current from another one of power supply unit bodies 9b to 9n tries to flow via the rectifying switching element 6 of the power supply unit body 9a.
