This paper proposes an analysis method of AC-AC direct converters which are Matrix converter et, al.. The proposed analysis method, is described by a switch matrix and instantaneous space vectors of the input voltage and the output voltage, is uniformly able to analyze the characteristics of the AC-AC direct converters, because the output voltage range and the controllability of input current are clearly defined. In addition, a novel circuit was invented by using the proposed analysis method. The novel circuit, called Delta converter, realizes VVCF operation and high input power factor regardless of load power factor.<br>In this paper, the proposed analysis method is applied to five types of the AC-AC direct converters and the features of each circuits are compared and discussed.
