Abstract (en)

[origin: WO2020025585A1] An inverter (1) having a DC/DC converter (4), which converts a direct voltage received from a direct-voltage source (3) into a DC link voltage of a DC link (5), a DC/AC converter (6), which converts the DC link voltage into an alternating voltage, having a monitoring unit (8), which monitors capacitors of the DC link (5) in order to protect against overvoltages, the monitoring unit (8) decoupling the direct voltage source (3) from the DC link (5) by controlling the DC/DC converter (4) in the event that an overvoltage occurs on at least one of the capacitors of the DC link (5).
