> transformers windings in vs windings out Transformers only apply to AC, where there is a fluctuating magnetic field. A transformer in a DC circuit is just a physically large (very low resistance) resistor. The standard practice to convert DC voltage (at least for these voltages) would be a buck converter, which is an active circuit.
