Abstract
A voltage step-up autotransformer topology and an AC-to-DC converter including such an autotransformer are provided. The autotransformer is configured to take, at input, a three-phase AC current (for example 115 VAC with a constant frequency), and to output nine output voltages, which are supplied to an 18-pulse rectifier bridge assembly so as to supply a high DC voltage (for example +270 VDC/−270 VDC). These are particularly suitable for AC-to-DC converters in the aeronautical sector.
