Abstract: A rectifier is configured to convert a three-phase AC voltage to a 12-pulse DC voltage, drawing a 12-pulse AC current from a three-phase network. The rectifier may comprise a first interleaved phase-leg, a second interleaved phase-leg, and/or a third interleaved phase-leg. Respective interleaved phase-legs may comprise positive portions configured to conduct positive current from a transformer towards a load, and negative portions configured to conduct negative current from the load back to the transformer. The rectifier may be configured to sequentially cycle respective interleaved phase-legs into positive and/or negative 120 conducting states over a 360 degree cycle to output the 12-pulse DC voltage. For example, during a first 120 degree conducting state a positive portion of the first interleaved phase-leg may conduct positive current towards the load, while a negative portion of a different phase-leg may conduct negative current back to the transformer.

Abstract: A converter for connecting a voltage source to a load includes a plurality of ICBT (integrated capacitor blocked transistor) cells configured as switches and connected in series to form a series connection path, a main capacitor connected across the series connection path, and a controller. Each ICBT cell includes a main transistor disposed in the series connection path and a series connected auxiliary transistor and auxiliary capacitor coupled in parallel with the main transistor. The controller is operable to develop a voltage across the main capacitor which exceeds a voltage rating of the ICBT cells, by switching the ICBT cells so as to commutate current within the individual ICBT cells without the ICBT cells providing active power to the load so that power flow is from the voltage source, to the main capacitor, to the load and not through the auxiliary transistors and the auxiliary capacitors.

Abstract: Among other things, one or more techniques and/or systems are provided for converting a three-phase AC voltage to a 12-pulse DC voltage, drawing a 12-pulse AC current from a three-phase network. A rectifier (200,336,436,536,636) may comprise a first interleaved phase-leg (202,326,426,526,626), a second interleaved phase-leg (204,328,428,528,628), and/or a third interleaved phase-leg (206,330,430,530,630). Respective interleaved phase-legs may comprise positive portions configured to conduct positive current from a transformer towards a load, and negative portions configured to conduct negative current from the load back to the transformer. The rectifier may be configured to sequentially cycle respective interleaved phase-legs into positive and/or negative 120 conducting states over a 360 degree cycle to output the 12-pulse DC voltage. For example, during a first 120 degree conducting state a positive portion of the first interleaved phase-leg may conduct positive current towards the load, while a negative portion of a different phase-leg may conduct negative current back to the transformer.
