    摘要: A multi-phase converter includes a plurality of phase paths. Each phase path includes at least one dc-link that is independent from every other phase path dc-link such that each output phase voltage is generated from a corresponding dc-link voltage source that can be different from every other phase voltage dc-link voltage source. A total dc-link voltage level is determined for each output phase voltage. A common-mode injection voltage is calculated based on all dc-link voltage levels and all phase reference voltages. Each phase path reference voltage is then adjusted based on the calculated common-mode injection voltage, such that each generated output phase voltage level is adjusted in response to its corresponding adjusted reference voltage.

    摘要: Authorized or unauthorized opening of access to equipment of a telecommunications network in a control center is detected on the basis of alarm messages. The telecommunication network is a mobile radio network or a hard-wired network. The control center monitors the access equipment and transmits alarm messages as a result of the access equipment being opened. A message is first transmitted by a signaling device to a signaling server before the access equipment is opened. Then the server, after receiving the message from the signaling device, generates an alarm-suppression information item. This alarm-suppression information item is evaluated in the control center, and, whenever an alarm message is received, this message is compared with the alarm-suppression information items and the alarm message is filtered in the event of a positive association.

    摘要: A multilevel converter includes a plurality of phase legs each having at least two inner switching devices, at least two outer switching devices, at least two clamping diodes, a split DC link and a switching device failure detection circuit. The switching device failure detection circuit includes a logic module for each of the switching devices, a voltage calculation module and a failure detection algorithm. The logic module generates a blocking state logic signal by comparing a switching device voltage and a threshold reference voltage and the voltage calculation module determines an expected voltage blocking state for each of the switching devices based on the gate drive signals of the switching devices and an output current direction. The failure detection algorithm detects a failure condition in any of the switching devices based on the blocking state logic signals and the expected voltage blocking states of the switching devices.
