PROBLEM TO BE SOLVED: To provide an inverter system whose driving power is reduced and a power supply system using the inverter system.SOLUTION: An inverter system 105 comprises an inverter group 3 and a controller 5. The inverter group 3 comprises: an inverter 31 that is a main inverter; and inverters 32 to 34 that are sub inverters. The controller 5 performs control so that output voltage from the inverter group 3 is within a reference range, by driving a stopped sub inverter of the inverters 32 to 34 when the output voltage from the inverter group 3 is lower than the reference range and stopping a driven sub inverter of the inverters 32 to 34 when the output voltage from the inverter group 3 is higher than the reference range.SELECTED DRAWING: Figure 2 |
