The transformer utilization factor (TUF) of a

rectifier 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 reverse operation (converting DC to AC) is performed by an Power ...

circuit is defined as the ratio of the DC power available at the load resistor to the AC rating of the secondary coil of a transformer.

T.U.F = \frac

The

VA

rating of the transformer can be defined as:

VA = V_ \dot I_ (For\ secondary\ coil.)

TRANSFORMER utilization factor for half wave rectifier is .287 or .3.
