| Abstract: | A novel single-phase three-level rectifier has been proposed in this paper.Detailed analysis of this circuit structure and working principle has been made.A switch function mathematical model has been built.With choosing 6 working patterns of the optimal combination,it makes this circuit emulate unit power factor.It brings stable output voltage,small ripple,and can realize DC side output capacitor voltage self-balance.The prototype experimental results demonstrate the validity and feasibility of this circuit. |
