# ^Ripple factor

### ^**Ripple factor**

The output obtained from a rectifier is the superposition of both ac & dc components. The ratio of ac component to the dc component in the rectified output is called the ripple factor it decides the effectiveness of a rectifier. i.e.

**ac power input**

It is the effective input power i.e.

**dc power output**

It is the effective output power across the load i.e.

**Rectifier efficiency**

It is defined as the ratio of dc output power to the applied ac input power i.e.
