To avoid confusion with split-phase motor start applications, it is appropriate to call this power distribution system a . 3-wire, single-phase, mid-point neutral. system. In North America, the high leg delta system allows single-phase 120 V loads and 240 V three-phase loads both to be served by the same three-phase, four-wire distribution system.

Switch-Mode Power Supplies. A variety of ac electronic equipment is powered internally by dc. In the early days of power supply design, the common single-phase power supply was linear. In Fig. 1-1, a schematic of a linear power supply, the rectifier stage utilizes a transistor (not shown) which operates in …

For single-phase power, the instantaneous power delivered to a load pulsates, but for three phase power, it is constant, which decreases generator vibration and increases generator life. Also, three-phase motors are more efficient and more reliable than single phase motors.
