There is described a communication structure for at least two solar inverters, having a transmission medium by means of which each of the at least two solar inverters is connected to a communication network with a first group of the solar inverters each being connected via an LAN interface to the communication network, and with a further group of the solar inverters being connected to the first group via serial interfaces. Two different network types are therefore provided with the first being suitable for standard LAN technologies with rapid data transmission over short distances, and with the second being suitable for interference-insensitive data transmission over long distances.

There is described a method for controlling a quenching device for a converter bridge with line regeneration, whereby the converter bridge controlled by a network-timed control circuit by ignition pulses is connected with its three inputs to the phases of a three-phase network and the two outputs of the bridge are connected to a direct-current motor which feeds, when operated as a generator, current back to the three-phase network via the bridge. The quenching device is controlled by a trigger unit which emits trigger pulses depending on the monitoring of electrical and temporary variables. The quenching device comprises, for each bridge half, a quenching condenser that can be charged by a charging circuit quenching voltage. The quenching condensers, in the event of quenching, can be connected to the bridge halves by means of switches that are controlled by the trigger unit.

There is described a method for controlling a quenching device for a converter bridge with line regeneration, whereby the converter bridge controlled by a network-timed control circuit by ignition pulses is connected with its three inputs to the phases of a three-phase network and the two outputs of the bridge are connected to a direct-current motor which feeds, when operated as a generator, current back to the three-phase network via the bridge. The quenching device is controlled by a trigger unit which emits trigger pulses depending on the monitoring of electrical and temporary variables. The device has measuring values 'direct output current' and/or 'supply voltages' used to determine characteristic values which are compared with theoretical characteristic values. Depending on the result of said comparison, the quenching device is optionally activated.

Re-use and platform independence of application software is achieved by using component types comprising an interface and a body. This is followed by automatically generating components based on the developed component types. The development process steps are preceded by an adaptation process step, during which the functionality of all component types is defined for all the platforms.
