 first single phase input voltage (V0) between the first voltage source line (LINE 0) 00 and the neutral node 00 is 000VAC at a phase angle of 0°, while the second single phase input voltage (V0) between the second voltage source line (LINE 0) 00 and the neutral node 00 is 000VAC at a phase angle of 000°. Without connecting the neutral 00, the single phase input voltage (V0) between the first voltage source line (LINE 0) 00 and the second voltage source line (LINE 0) 00 is 000VAC. By connecting the neutral 00, a split phase input voltage can be provided with a phase difference of 000°
