A buck-boost ac-ac converter with inverting and non-inverting operations is proposed. The non-inverting operation
activity can be utilized to remunerate voltage hang, and altering activity can be utilized to repay voltage swell. Along these lines,
the proposed converter as a unique voltage restorer is equipped for making up for both voltage hang and swell in a wide range.
It’s essential exchanging cell is a unidirectional buck circuit, inferable from which it has no shoot-through concerns. It
accomplishes safe substitution without utilizing RC snubbers or delicate recompense techniques.
