Why do we convert AC to DC?
We need to convert AC to DC because of below facts: AC signals can not be stored and DC power or signals can be stored.Thus,to store the electrical energy we need to convert it into DC. … AC can be transported over long distances because of it's frequency and dc can not be transported as dc has zero frequency.
How is AC converted to DC?
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification, since it "straightens" the direction of current.
