Abstract
A circuit system having at least two inverter modules connected in parallel, each of which includes an inverter circuit having power semiconductor circuit breakers and a gate driver circuit for controlling the power semiconductor circuit breakers; the gate driver circuit of a first inverter module includes a signal transmission circuit via which a control signal is transmittable from a low-voltage side to a high-voltage side, and a first driver output terminal which is electrically connected to the first driver input terminals of the gate driver circuits of the inverter modules connected in parallel, and via which the high-voltage side control signal or a control signal deduced therefrom is transmittable to the gate driver circuits of the inverter modules connected in parallel. The power semiconductor circuit breakers of the inverter circuits of the inverter modules, connected in parallel to the first inverter module, are controlled based on the transmitted control signal.
