Transformer utilization factor

The transformer utilization factor (TUF) of a rectifier 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.^[1][2]

${\displaystyle T.U.F={\frac {P_{odc}}{VA\ rating\ of\ transformer}}}$

The ${\displaystyle VA}$ rating of the transformer can be defined as: ${\displaystyle VA=V_{r.m.s}{\dot {I}}_{r.m.s}(For\ secondary\ coil.)}$TRANSFORMER utilization factor for half wave rectifier is .287 or .3.
