Gate control of thyristor converters for reversibly driving a D.C. electric motor

摘要: A gate control for thyristor converters connected in opposition to reversibly drive a D.C. electric motor which one of the operates as rectifier and other remains still when runs forward, vice versa. The includes an operational amplifier carry out current generate output therefrom follows armature voltage during switchover between prepare reverse rotation motor. converter, momentarily inverter feed energy from back A.C. supply thereof reduce speed, is controlled enable its coincide substantially with so not cause excessive rushing into at instant switchover.
