摘要： A converter comprises a plurality of controllable two-pole sub-modules connected in series. At least some of the sub-modules each comprises a first and a second sub-module connection, a first, a second, a third and a fourth controllable switch, and a storage dipole, which comprises a first and a second dipole connection, an energy store and a controllable switching device, wherein the controllable switching device has a first selectable switching state, in which the storage dipole outputs no energy, and a second selectable switching state, in which the store of the storage dipole can take up or discharge energy. The sub-module has a selectable conduction state, in which the controllable switching device of the storage dipole assumes the first switching state and the first to fourth switches are switched such that a current flows through the sub-module on two parallel branches.

摘要： External power supply system includes an electrical storage device, motor, inverter that drives the motor by using electric power of the electrical storage device, and a control device controls the inverter. The inverter includes a first and second switching elements connected in series with each other between a positive and negative electrode power supply lines. A connection-node of the first and second switching elements is connected to one corresponding stator coil. The control device inputs signals to the inverter to drive the inverter such that voltage at the neutral point becomes a predetermined value. The control device compensates for signals in dead time period, the period in which off-state signals are supplied to the first and second switching elements, on the basis of current that is input from the connection-node to one corresponding stator coil or output from one corresponding stator coil to the connection-node while an engine is driven.

摘要： An electrical system includes a converter having an H-bridge. The H-bridge includes a first set of transistors electrically connected in series and a second set of transistors electrically connected in series. The first set and the second set of transistors are electrically connected in parallel. The H-bridge defines three available switching states such that a common mode voltage across the H-bridge at each switching state is zero. A method for reducing electromagnetic interference (EMI) in pulse-width modulation (PWM) converters includes diagonally switching transistors of the H-bridge. Diagonally switching the transistors of the H-bridge includes constraining available switching states of the H-bridge to only include the switching states with zero common-mode voltage such that common-mode voltage on an AC output side of the H-bridge is zero.
