Wechselrichter mit Netztrennstelle und Isolationswiderstandsmessung sowie Verfahren zur Messung eines Isolationswiderstandes

verfasst von: Jens Friebe, Burkard Müller, Martin Putz
Abstract: An inverter including a circuit arrangement configured to measure an insulation resistance is disclosed. The inverter includes at least one half-bridge including at least two switching elements extending between respective end points, and a grid disconnection point comprising a series circuit comprised of two disconnection devices. The series circuit is arranged between a center point of the half-bridge and an AC voltage terminal of the inverter, which AC voltage terminal is configured to connect to a phase conductor or a neutral conductor of an AC voltage grid. The circuit arrangement includes a resistor and a voltage measurement apparatus. The resistor is arranged electrically in parallel with one of the disconnection devices and the voltage measurement apparatus is arranged electrically between the output-side terminal of the resistor and one of the end points of the half-bridge.
