A transformer circuit (100) for an electric vehicle comprises an input (104); an output (106); and a transformer (108) located between the input and the output. The transformer comprises a primary winding (110) connected to the input; and a secondary winding (102) connected to the output. At least one of the primary winding and the secondary winding comprises a first split winding (112) and a second split winding (114). The first split winding is configured for carrying a higher current than the second split winding. The circuit comprises switching means (116) configured to, where the primary winding comprises the first and second split windings, selectively connect the first split winding to the input, or connect the first and second windings in series to the input, and where the secondary winding comprises the first and second split windings, selectively connect the first split winding (112) to the output (106), or connect the first and second split windings (112, 114) in series to the output.
