• This paper proposes a novel control method for an interface converter that is using an indirect matrix converter (IMC) with a DC power supply. The proposed converter is constructed based on an indirect matrix converter and a converter that combined the function of a boost type converter and a step-down type converter. The proposed converter connects an active snubber to the DC link part of IMC along with a boost type converter. The voltage transfer ratio from the AC power sources to the load can be improved by this active snubber. In addition, the proposed control method able to control the power distribution ratio and the output voltage at a same time. The basic operation of the proposed method has confirmed by simulation and experimental results.
