FIELD: electricity.
SUBSTANCE: disclosed is a method for turning on and off a four-line hybrid electric starter, which is composed of three single-phase thyristor with natural commutation key, connected in parallel per phase to three-phase contactor contacts.
EFFECT: method provides turning on without transient currents and voltages in electrical networks and electricity consumers, and turn-off without occurrence of an arc between contacts of three-phase contactor.
