Half Waving and Need of Free Wheeling Diode in Half Wave Controlled Rectifier with R-L load
Half Waving and Need of Free Wheeling Diode in Half Wave Controlled Rectifier with R-L load
Half Wave Controlled Rectifiers ⇒ Half Waving
Free wheeling takes place due to stored energy in inductive load.
Problem of half waving can be overcome by including a free wheeling diode across inductive load in the HWCR circuit.
Advantages of Free Wheeling Diode
The input power factor is improved.
Load current waveform becomes more smoother.
The load performance is improved due to smoother load current.
The output voltage/Load voltage never becomes negative.
