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.
