Engineering: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]

$T . U . F = \frac{P_{o d c}}{V A r a t i n g o f t r a n s f o r m e r}$

The $V A$ rating of the transformer can be defined as: $V A = V_{r . m . s} {\dot{I}}_{r . m . s} (F o r s e c o n d a r y c o i l .)$ TRANSFORMER utilization factor for half wave rectifier is .287 or .3.
