摘要： A voltage regulator having a multiple of main stages and at least one accelerated voltage regulator (AVR) bridge is provided. The main stages may respond to low frequency current transients and provide DC output voltage regulation. The AVR bridges are switched much faster than the main stages and respond to high frequency current transients without regulating the DC output voltage. The AVR bridge frequency response range can overlap with the main stage frequency response range, and the lowest frequency to which the AVR bridges respond may be set lower than the highest frequency to which the main stages respond.

摘要： An electrical converter (10) comprises a main stage (12) adapted for converting a DC voltage into an intermediate voltage comprising at least two voltage levels, a filter cell stage (14) with a filter cell (30) for each phase of the intermediate voltage, each filter cell (30) being adapted for adding or subtracting a cell voltage of the filter cell (30) to the intermediate voltage, and a pre-charge circuit (44) adapted for pre-charging the filter cells (30) and a DC link (20) of the main stage (12) and comprising an auxiliary power source (46) connected between one phase of an output (34) of the electrical converter (10) and a neutral point (NP) of said DC link (20) of the main stage (12), wherein all phases of the output (34) of the electrical converter (10) are connected via an electrical load (16). A method for pre-charging filter cells (30) during a start-up of an electrical converter (10) comprises a pre-charging of the filter cells (30) comprising the steps of: switching the main stage (12) such that all phases of the output (24) of the main stage (12) are directly connected to the neutral point (NP) of the DC link (20) of the main stage (12); switching at least one of the filter cells (30) into a rectifying state, in which a rectified current flows through a cell capacitor (38) of this filter cell (30); and switching the pre-charge circuit (44) on and charging the cell capacitor (38) of said at least one filter cell (30) by the pre-charge circuit (44), until a nominal cell voltage is achieved at the cell capacitor (38) of this filter cell (30).
