Abstract

An overvoltage limitation device, for an alternating current (AC) voltage generating system having an inverter circuit unit configured to supply power to a load with dynamic load impedance, includes: input connections for connection to the inverter circuit unit, output connections for connection to an intermediate circuit voltage unit connected to the inverter circuit unit, a rectifier including an alternating current connection and a direct current connection connected to the output connections, and an AC voltage converter including a primary side connected to the input connections and a secondary side connected to the alternating current connection. The overvoltage limitation device is configured such that, when peak values of an AC voltage exceed a first predetermined value at the input connections, power is transported from the input connections via the AC voltage converter and the rectifier to the output connections, and thus the AC voltage is limited to a second predetermined value.
