| Abstract |
This paper proposes a novel control method for an interface converter using an indirect matrix converter with three power supplies, which consist of two AC and one DC supplies. An active snubber circuit in the indirect matrix converter is used as an interface with the DC power supply. The proposed control method is based on the indirect control method with a triangular carrier wave [10]. Therefore the proposed method can be easily applied to a DC/DC converter. In addition, this paper proposes reducing the number of switching during one carrier period for the inverter stage converter. In the proposed method, the inverter stage carrier is controlled asymmetry to reduce the switching times in the inverter stage. To apply the proposed method, the switching loss of the inverter stage can be decreased to 2/3 times in comparison with a conventional method. The validity of the proposed method is confirmed by simulation and experimental results. |
