In electrical power engineering, multi-phase alternating current refers to various power systems with different numbers of phases, such as:

• Three-phase alternating current , also colloquially three-phase current, can be found in the field of electrical energy supply
• Two-phase alternating current , with two-phase stepper motors
• Five-phase alternating current , for supplying special stepper motors with usually 72 ° phase angle
