Description : Define PIV, TUF, ripple factor, efficiency of rectifier.

Last Answer : PIV: Peak Inverse Voltage (PIV) is defined as the maximum negative voltage which appears across non-conducting reverse biased diode. TUF : Transformer Utilization Factor (TUF) is defined as the ratio of DC output ... Efficiency of rectifier: η = DC output power/ AC input power = PLdc / Pac

Description : Define ripple factor and PIV of HWR

Last Answer : Peak Inverse Voltage (PIV) or Peak Reverse Voltage (PRV) refer to the maximum voltage a diode can withstand in the reverse-biased direction before breakdown. Also may be called Reverse Breakdown Voltage.

Description : Define ripple factor and PIV of diode.

Last Answer : 1. Ripple factor: It is define as ratio of R.M.S. value of AC component to the DC component in the output.  2. PIV : It is maximum reverse voltage that diode can withstand without destroying junction.
