Wani ita ce kofin tsari na filta (kofin tsari) da ya yi karfin kananan da take bayar voltage da ya zama duwawo ko zuwa biyu idan kowane wata daga cikin abubuwan da ake baka. A wannan sashe, za mu iya nemi bayanai game da full-wave voltage doubler, half-wave voltage doubler, voltage tripler da kuma quadrupler.

Half Wave Voltage Doubler

A taka bayyana abin da ke faru, diagram mai yadda ake gudanar da shi da kuma abin da ke fuskantar. Hakan, duk lokacin da alamar hanyoyi, D1 diode ya gudanar da diode D2 yake a kan gida. A wannan lokaci, capacitor (C1) ya ji VSmax (peak 2o voltage). Duk lokacin da alamar hanyoyi, D2 diode ya gudanar da D1 diode yake a kan gida. A wannan lokaci C2 ya faru.

Duk lokacin da alamar hanyoyi, D2 yake a kan gida (open circuited). A wannan lokaci C2 capacitor ya fito a kan abinci da kuma voltage a kan wannan capacitor ya fito.

Amma idan ba a kan wannan capacitor abinci, don haka duka mafi capacitor suna zama a kan gida. Yana nufin C1 ya ji VSmax da kuma C2 ya ji 2VSmax. Duk lokacin da alamar hanyoyi C2 ya ji 2VSmax). A lokacin da alamun hanyoyi, abin da ya faru ne a kan C2 ta faru. Hakan, frequency ripple ce sama da frequency signal. DC output voltage da ke 3kV ana iya samun shi daga wannan circuit.

Full Wave Voltage Doubler

Abin da ke faru game da full-wave voltage doubler an bayyana a nan.

Diagram mai yadda ake gudanar da shi da kuma abin da ke fuskantar an bayyana a cikin figure 3. Hakan; duk lokacin da alamar hanyoyi, D1 yake a kan gida da kuma C1 ya ji VSmax(peak voltage). A wannan lokaci, D2 yake a kan gida. Duk lokacin da alamar hanyoyi, D2diode yake a kan gida da kuma C2 ya ji. Idan ba a kan abinci a kan terminalon da ake faru, voltages duka mafi capacitorssunan iya samun shi a kan output voltage. Idan ake faru abinci a kan terminalon, output voltage.

Zan iya neman, cewa duka mafi half-wave da kuma full-wave voltage doubler suna iya bayar 2VS MAX a kan output. Ba a tabbas transformer da ke centre-tapped. Peak inverse voltage rating of diodes ce 2VS MAX. Amma idan a yanayi half wave voltage doubler, full-wave voltage doubler yana iya filter high frequency ripples da kuma output ripple frequency ce sama da twice the supply frequency. Amma masu sauki a kan full-wave voltage doubler shine; ba a kan input da kuma output, common ground ba a cikin ba.

Voltage Tripler and Quadrupler

Tare da hanyoyin extension of half-wave voltage doubler circuit, ana iya gudanar da sabon voltage multipliers (Tripler, Quadrupler etc). Idan leakage da abinci su ne kadan, ana iya samun DC voltages da suka fiye waɗanda suke da sections da suke step-up (increase) the DC voltage.

Hakan; duk lokacin da alamar hanyoyi da kuma alamar hanyoyi, yana da hanyoyin half-wave voltage doubler. Duk lokacin da alamar hanyoyi, D1 da D3 suka gudanar da C3 ya ji 2VSmax. Duk lokacin da alamar hanyoyi, D2 da D4 suka gudanar da C4 ya ji 2VSmax. Idan ake gudanar da wasu
