CALCULATIONS: Full Wave Rectifier

  • From N 1 * V 2 = N 2 * V 1
  • N 1= Number of turns in Primary transformer , N 2= Number of turns in Secondary transformer
  • V 1= Primary Voltage , V 2 = Secondary Voltage
  • Here, V 2 = V m,V rms= V m/ √2
  • V dc= (2 * V m)/ π
  • Ripple factor of Full wave Rectifier is, γ = √(V rms/ V dc) 2 - 1
  • Theoretical Value of Ripple Factor ≈0.48
  • Experimental Value of Ripple factor ,
