Method for establishing a supply voltage and inverter

A voltage supply system, comprising:

• a plurality of independently controlled virtual synchronous machine (VISMA) power inverters connected to a DC voltage, wherein outputs of the plurality of VISMA power inverters are connected together to a load, the load requiring more power than a single one of the plurality of VISMA power inverters is able to deliver, and
• a synchronization event generator connected to a synchronization event input of each VISMA power inverter, wherein the synchronization event generator is configured to transfer a synchronization event to all of the plurality of VISMA power inverters,
• wherein each respective VISMA power inverter is configured to:
• build up a VISMA control of an output AC voltage at the output thereof depending on a predetermined target mains voltage,
• synchronize a phase position of the output AC voltage to a first synchronization event that is received at the synchronization event input from the synchronization event generator, and
• build up a mains voltage simultaneously with all of the plurality of VISMA power inverters with a matched phase position after synchronization of the phase position has taken place.
