A transformer with twelve cores, a first six arranged in parallel rows of three, a second six, in parallel rows of three at right angles to the first six and positioned between the first and second, and second and third cores of each row of the first six; four coil assemblies each comprising a primary winding and a secondary winding, each of the coil assemblies embracing legs of four cores, the primary and secondary coils being electrically connected in parallel to like coils in other coil assemblies in a 180 DEG out of phase connection. Preferably, each coil assembly includes a capacitor coil, and the capacitor coils are series connected to one another at opposite corner poles so that each capacitor coil voltage is added to each other capacitor coil, the first and fourth of said capacitor coils being electrically connected to different sides of the line voltage, and the second and third of said capacitor coils being electrically connected in series to a capacitor.
