PURPOSE:To provide a parallel operation system for power supply units wherein regulation of output voltage from each power supply unit is facilitated and normal current balance function is kept even upon stoppage of one power supply unit. CONSTITUTION:The parallel operation system is constituted so that output voltages of a plurality of power supply units PWR1, PWR2, PWR3 can be regulated easily at one point. It is further constituted such that the current balance function is effective between remaining power supply units PWR1, PWR2, PWR3 upon stoppage of one of them. |
