संधारित्र फिल्टरसह हाफ वेव्ह रेक्टिफायरसाठी रिपल फॅक्टर
\(Ripple\;factor,(r) = \frac{1}{{2\sqrt 3 fC{R_L}}}\)
संधारित्र फिल्टरसह फुल वेव्ह रेक्टिफायरसाठी रिपल फॅक्टर
\(Ripple\;factor,(r) = \frac{1}{{4\sqrt 3 fC{R_L}}}\)
कॅपेसिटर फिल्टरसह रेक्टिफायरची व्यवस्था खाली दर्शविली आहे:
XC आणि R ची मूल्ये अशी निवडली जातात जेणेकरून |XC| << RL
म्हणजे, \(\frac{1}{{{\omega _o}C}} < < {R_L}\) हाफ वेव्ह रेक्टिफायरसाठी
\(\frac{1}{{2{\omega _o}C}} < < {R_L}\) फुल वेव्ह रेक्टिफायरसाठी
- संधारित्र (C) आणि RL समांतर असल्याने, ते प्रवाह विभाजक परिपथ तयार करतात.
- उच्च वारंवारतेसाठी संधारित्र शॉर्ट परिपथ म्हणून काम करेल, म्हणजे बहुतेक प्रवाह Iac संधारित्रामधून वाहतो आणि एक अतिशय लहान AC प्रवाह RL मधून जातो.
- त्याचप्रमाणे, संधारित्र DC साठी ओपन परिपथ म्हणून वर्तन करत असल्याने, IDC हा RL मधून प्रवाहित होईल.
खालील तक्ता FWR आणि HWR साठी भिन्न संबंध दाखवते.
