Abstract: A converter for conversion between three-phase AC and a DC signal may include three phase terminals, a first and second DC terminal, conversion circuitry for conversion between three phase voltages of the three-phase AC signal and a first and second intermediate voltage at first and second intermediate nodes, and first and second buck circuits. The buck circuits each have three devices that are actively switchable for connecting switch-node terminals to any one of the three phase terminals. The first buck circuit includes a second switching device connected between the first intermediate node and the first switch-node terminal, and a first filter inductor connected between the first switch-node terminal and the first DC terminal. The second buck circuit has another second switching device connected between the second intermediate node and the second switch-node terminal, and a second filter inductor connected between the second switch-node terminal and the second DC terminal.

Abstract: An electrical converter includes first and second converter stages, an output filter, and a controller having a first mode for converting a three-phase AC signal into a DC signal. The first converter stage has a three-phase bridge rectifier connecting three phase terminals to an upper intermediate node and a lower intermediate node, and a phase selector having first switches connecting the terminals to a middle intermediate node. The second converter stage includes a switch node connected to the middle intermediate node and a pair of second switches connecting the switch node to one of the DC terminals. In a second mode, the first switches are operated while keeping the upper or lower intermediate node disconnected from all the phase terminals to allow a current to flow between the middle intermediate node and the output filter, allowing for stepwise increasing a voltage across the DC terminals during start-up.

Abstract: An electrical converter may include AC terminals, a first and second DC terminal, and converter modules. Each of the converter modules has an AC node. The second DC terminal forms a common node of the converter modules. A connection between the AC nodes of the converter modules and the AC terminals is reconfigurable allowing the electrical converter to operate according to a first mode of operation converting between a first AC signal having a first plurality of phase voltages and the DC signal, in which the converter modules are grouped in first groups, and according to a second mode of operation converting between a second AC signal having a single-phase voltage and the DC signal, in which the converter modules are rearranged in second groups. The electrical converter is configured to operate multiple converter modules assigned to a same group of the first groups and the second groups in parallel.

Abstract: A three-phase AC to DC converter includes a first converter stage for converting between three phase voltages at three phase terminals and a first signal at a first intermediate node and a second intermediate node. A phase selector is configured to selectively connect the three phase terminals to a third intermediate node. The converter includes a second converter stage, a DC link connecting the first and second converter stages, and a galvanically isolated DC/DC converter stage having a first side connected to output nodes of the second converter stage and a first common node. A second side of the DC/DC converter stage is galvanically isolated from the first side. The first common node is connected to the third intermediate node. The difference of a first current applied to the DC/DC converter at output nodes of the second converter stage is provided at the third intermediate node.

A current injection circuit has second active switches. In a first mode, the first active switch and the second active switches are operated through PWM. In a second mode, the third and fourth intermediate nodes are continuously connected to the first and second DC terminals such that the second converter stage is inoperative and the second active switches are operated through PWM.
