    摘要: A plug-in jumper for terminal blocks is provided for elastic engagement in openings in busbars and for electrical contact-making of the busbars of at least two junction and/or connecting terminals. The plug-in jumper includes a jumper bar having a bar strip and several plugs which are connected to the bar strip. Each plug has at least two contact legs located essentially parallel to one another, of which at least one is made elastic. The plug-in jumper makes it possible to electrically interconnect different busbars of different terminal blocks since the plugs have two contact areas which are located on top of one another for contact-making of two busbars of two junction and/or connecting terminals which are located next to one another, wherein the two busbars are located on a different planes.

    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: A control system for a multilevel converter includes a differential mode current regulator, a neutral point (NP) controller and a PWM controller for generating switching pulses for the multilevel converter. The differential mode current regulator generates reference voltage command signals based on a difference between reference current command signals and actual current command signals, and the NP controller determines a modified neutral point current signal in response to a DC link voltage unbalance. The NP controller utilizes the modified neutral point current signal to generate a common mode reference voltage signal. The switching pulses are generated by the PWM controller based on the reference voltage command signals and the common mode reference voltage signal.
