Abstract
Cosine-intersect method is adopted widely in the control of digital AC/AC converter, But for the sinusoidal current AC/AC converter, there are some defects in the cosine-intersect method. The slope approximation control method, as a new control method, which calculates and controls the load current directly, can improve the qualities of output current, and reduce the harmonic contents obviously.
