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. T . U . F = P o d c V A r a t i n g o f t r a n s f o r m e r {\displaystyle T.U.F={\frac {P_{odc}}{VA\ rating\ of\ transformer}}} The V A {\displaystyle VA} rating of the transformer can be defined as: V A = V r . m . s I ˙ r . m . s ( F o r s e c o n d a r y c o i l . ) {\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.

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

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