“…1) of VSIs operating in parallel for the autonomous system has been applied. The master unit provides the reference current for itself and for all the slave units, and slave units only realize this reference current control [1,3]. In consequence, a master unit is controlled in the system with both the outer voltage control loop and inner current control loop, whereas slave units are controlled by using only the inner current control loop.…”

The paper presents the single phase UPS system with galvanic separated DC-AC-DC-AC converters operating in parallel. The CAN physical layer based system of communication between converters has been developed and applied, which allow to utilize a decentralized masterslave control providing high availability factor of the whole UPS system. The control system of particular converters has been developed to ensure a high quality of the output voltage for both linear and nonlinear load. The selected simulations and experimental results obtained for 5kVA prototype modules are presented.

“…The redundancy and reduction of SPOFs is possible to obtain only by using a modules which operate in parallel supplying a common loads [1], [2], [3], [4]. Such a configuration makes it necessary to implement an appropriate hardware and software solutions, in particular: control of parallel operating voltage source inverters (VSI) with the LC output filter, which constitute an output converter of each UPS module, reliable, disturbances immune communication between particular modules.…”

The paper presents the single phase uninterruptible power supply (UPS) system with galvanic separated DC-AC-DC-AC converters operating in parallel. The CAN physical layer based system of communication between converters has been developed and applied, which allow to utilize a decentralized master-slave control providing high availability factor of the whole UPS system. The control system of particular converters has been developed to ensure a high quality of the output voltage for both linear and nonlinear load. The selected simulations and experimental results obtained for 5kVA prototype modules are presented. Keywords-uninterruptible power supply, decentralized control, parallel operation of the voltage source inverters
