A method for connecting an energy generation installation to a medium-voltage grid includes determining a calibration factor for adjusting first voltage values to second voltage values by a controller of the energy generation installation. During an idle state of a medium-voltage transformer, the first voltage values are detected at a capacitive voltage divider, arranged on the medium-voltage side of the medium-voltage transformer, and the second voltage values are detected by a voltage detection means, arranged on the low-voltage side of the medium-voltage transformer. The method further includes closing a circuit breaker arranged on the medium-voltage side of the medium-voltage transformer by the controller of the energy generation installation, when voltage values determined at the capacitive voltage divider exceed a first threshold value after the calibration factor has been applied.

A hybrid traction inverter can include a plurality of power switches configured to supply current to a motor of an electric vehicle and a controller. The plurality of power switches can include a first power switch and a second power switch, the first power switch and the second power switch being of different types. The controller can determine that a current associated with the plurality of power switches exceeds a threshold current. Responsive to determining that the current associated with the plurality of power switches exceeds the threshold current, the controller can control the plurality of power switches such that the first power switch turns on before the second power switch turns on during a switching cycle.
