1 Answer

Answer :

(i) Ripple Factor - Ripple factor (γ) may be defined as the ratio of the root mean square (rms) value of the ripple voltage to the absolute value of the DC component of the output voltage. 

(ii) Efficiency- Rectifier efficiency is defined as the ratio of DC power to the applied input AC power. Rectifier efficiency, η = DC output power/input AC power 

(iii) Peak inverse voltage: For rectifier applications, peak inverse voltage (PIV) or peak reverse voltage (PRV) is the maximum `reverse voltage that a diode can withstand without destroying the junction 

(iv) Transformer Utilization Factor (TUF) : Transformer Utilization Factor (TUF) is defined as the ratio of DC power output of a rectifier to the effective Transformer VA rating used in the same rectifier. Effective VA Rating of transformer is the average of primary and secondary VA rating of transformer.
