  • Publication number: 20250023487
    Abstract: A power converter system includes a DC voltage source, a control system, a multilevel inverter and a balancing circuit connected to the DC voltage source, and at least two DC link series connected capacitors connected between a positive and a negative voltage supply line (V+, V?) of the DC voltage source and having a mid-point therebetween. The balancing circuit comprises a plurality of switches that are connected in series between said positive and a negative voltage supply line (V+, V?), the plurality of switches arranged in a first pair of switches and a second pair of switches. A flying capacitor is connected between a mid point of the first pair of switches and a mid point of the second pair of switches, and an inductor is connected between said DC link capacitor mid point and a mid point between the first pair of switches and second pair of switches.

  • Patent number: 11973446
    Abstract: Linear electric motor comprising a stator comprising a plurality of stator segments and a drive system comprising at least one pair of drive units, a first drive unit of said pair connected to a first stator segment and a second drive unit of said pair connected to a second stator segment adjacent the first stator segment, the drive units connected to a DC voltage source, each drive unit comprising a DC input circuit section and a multi-level inverter connected to the DC voltage source via the DC input section, the multi-level inverter comprising a multiphase output connected to coils of the corresponding stator segment. The DC circuit section of the drive units comprises at least two link capacitors (C1, C2) connected between a positive and a negative voltage supply line (V+, V?) and having a mid-point therebetween.
