摘要： An inverter includes at least one relay disposed in an interior of the inverter. The relay is configured to connect the inverter to a grid phase or to disconnect the inverter from the grid phase. A temperature sensor is configured to measure an interior temperature of the inverter. A control unit is configured to actuate the relay, to determine the interior temperature by using the temperature sensor, and to calculate a switching time for the relay in dependence on the interior temperature.

摘要： An active neutral point clamped topology based converter includes a plurality of input terminals, an output terminal, a choke, a plurality of switching devices and a control unit. The control unit generates control signals for the switching devices of the converter in such that an SiC switch can be used with low reverse voltage.
