Current-Dependent Capacitor Voltage Control of Parallel Autonomous UPS Systems
This paper proposes a novel autonomous control scheme for equal load current distribution between n parallel-connected, LCL -based, three-phase online uninterruptible power supply (UPS) modules. The control is based on regulating the reference voltage of the filter's capacitor of each inverter...

| description | This paper proposes a novel autonomous control scheme for equal load current distribution between n parallel-connected, LCL -based, three-phase online uninterruptible power supply (UPS) modules. The control is based on regulating the reference voltage of the filter's capacitor of each inverter as a function of its own output current. The control is achieved without exchanging information between the inverters. The load voltage is maintained fixed at the specified reference value. The control method is fast, precise, and robust against load variations. The validity of the proposed method is verified experimentally and by simulation on a system of two parallel inverters under different load conditions, including step-load and nonlinear load. |
