Three Phase Synchronous Boost Rectifier

In this paper we will analyze two systems, one synchronous and one nonsynchronous, for drive and recover energy from a three-phase motor (a three phase motor can be used as an electric generator according to the mechanical power applied to its shaft) and we will propose a more efficient circuit to drive a three-phase motor and recover energy from the motor. The paper is a survey and represent the preliminary work in achieving the knowledge for developing a practical solution for to make the system more efficient.
