Digital synchronization system for the control of self-controlled synchronous machine converters

This paper presents a study and an implementation of digital synchronization for the control of a three-phase converter-inverter driving a self-controlled synchronous motor. Beginning with given performance specifications, a study is carried out to look for the solution to various problems encountered in the production of a firing angle reference in the case of a variable frequency and perturbated network. A completely digital solution is presented. This solution permits one to obtain synchronization and a real time clock.<
