METHOD AND DEVICE FOR OVERVOLTAGE LIMITING OF AN AC VOLTAGE GENERATING ARRANGEMENT

摘要

The invention relates to a method and a device for overvoltage limiting of an output voltage at the output of an AC voltage generation arrangement (131) with an inverter circuit unit (14) by means of a surge-limiting device (1), comprising: - two input terminals (11, 12) for connection to the inverter circuit unit; - two output terminals (21, 22) for connection to an intermediate circuit voltage unit (20) of the AC voltage generation arrangement; - a rectifier device (2) connected to the output terminals; - an AC voltage converter device (3) connected to the input terminals and the rectifier device, wherein, in the case of exceeding positive and negative AC voltage peak values over a predetermined amount at the input terminals, power is transported from the input terminals via the AC voltage converter device and the rectifier device to the output terminals and thus the AC voltage is limited at the input terminals to a further predeterminable amount.
