Definations:

01)Form factor: The ratio of the root mean square value to the average value of an alternating quantity (voltage or current) is called Form Factor.

02)Peak Factor or Crest factor: Peak Factor is defined as the ratio of maximum value to the R.M.S value of an alternating quantity (voltage or current).

03)Ripple Factor: The ripple factor formula is defined in terms of the RMS value  and the average value of the rectifier output.

$$ Ripple Factor= \sqrt{\verb!(Form Factor)^2! -1} $$

04)Peak Inverse Voltage: Peak Inverse Voltage (PIV) or Peak Reverse Voltage (PRV) refer to the maximum voltage a diode or other device can withstand in the reverse-biased direction before breakdown.

05)Transformation 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.

06)Efficiency: It is the ratio of DC output power to the AC input power.

Efficiency=DC Output Power/AC Input Power {Described in figure step1}

DC Output power use current avg. value whereas AC Output power use rms value of current in formula.
