Abstract :
This paper proposes a state-variable description and analysis of a DC-rail parallel resonant zero voltage transition (ZVT) voltage-source three-phase inverter feeding a permanent synchronous motor drive. In this DC-rail ZVT inverter, consists of two major parts: a ZVT resonant converter and an three-phase inverter. The DC-rail inverter is operated at a higher frequency and has higher efficiency than traditional inverters. A three-phase 1.1 kW 20 kHz DC-rail ZVT inverter has been constructed and successfully tested to feed a permanent magnet synchronous motor drive based on a field-oriented control. State variable description and analysis, simulation and implementation of the whole system are described The experimental results not only validate the theoretical development but also prove that this new system has better performance than traditional systems
