High efficient two switch auxiliary resonant DC link three-phase PWM inverter and two switch auxiliary resonant commutated bridge leg link three-phase PWM rectifier

In this paper, a new conceptual circuit configuration of three-phase voltage source type soft switching PWM AC/DC-DC/AC converter using IGBT module, which is composed of one ARCBL circuit and one ARDCL circuit is presented. In addition, the operating performances of proposed soft switching AC/DC-DC/AC converter treated here are evaluated on the basis of experimental results in 50kVA setup. Furthermore, the power loss analysis and operating performance of proposed soft switching AC/DC-DC/AC conversion system are evaluated from the simulation and experimental results.
