Peak Rov Qab Voltage los yog PIV yog qhov siab tshaj qhov tshwm sim hla p-n kev diode thaum nws tsis ua haujlwm. A diode tsis txhob ua thaum nws tau thim rov qab. Qhov no txhais tau tias ncov rov qab qhov hluav taws xob yog qhov siab tshaj plaws thim rov qab tsis ncaj ncees qhov hluav taws xob hla lub diode terminals thaum nws muab tso rau hauv Circuit Court.
Tib neeg tseem nug, PIV ntawm diode yog dab tsi?
Peak Rov Qab Voltage ( PIV ) lossis Peak Reverse Voltage (PRV) xa mus rau qhov siab tshaj plaws a diode lossis lwm yam cuab yeej tuaj yeem tiv taus kev thim rov qab-ua ntej kev puas tsuaj. Kuj tseem tuaj yeem raug hu ua Rov Qab Raug Rho Tawm Voltage.
Ib yam nkaus, PIV ntawm diode hauv ib nrab yoj rectifier yog dab tsi? Cov PIV sawv rau ncov rov qab qhov hluav taws xob hais txog qhov rectifier hluav taws xob tivthaiv. Qhov xwm txheej nthuav tawm qhov txwv qhov hluav taws xob uas tau txiav txim siab rectifier tuaj yeem tiv taus thaum qhov tam sim no hauv rectifier yog rov qab biased. Cov rectifier muaj PN txuas diode uas tso cai rau kev khiav tsis ncaj ntawm qhov tam sim no.
Qhov thib ob, PIV ntawm lub diode nyob rau hauv tag nrho yoj rectifier yog dab tsi?
Ncov siab tshaj qhov hluav taws xob ( PIV ) yog qhov siab tshaj plaws qhov muaj peev xwm ua tau thoob plaws a diode thaum nws yog rov qab-biased. Thaum xub thawj ib nrab -cov khoom siv piv txwv li thaum sab saum toj ntawm lub tshuab hloov pauv thib ob winding yog qhov zoo, diode D1 ua thiab muab yuav luag xoom tsis kam.
Yuav ua li cas yog tias qhov siab tshaj qhov hluav taws xob PIV qhov ntsuas ntawm diode dhau?
Raws li lub ntsiab lus dav siv rau semiconductor diodes , Ncov Rov qab Voltage (PRV) lub Peak Rov Qab Voltage ( PIV ) yog qhov siab tshaj plaws qhov hluav taws xob tias a diode tuaj yeem tiv taus qhov rov qab tsis tas yuav tawg lossis avalanching. Yog qhov no qhov hluav taws xob yog tshaj cov diode tej zaum yuav raug rhuav tshem.

PIV ntawm diode hauv Fwr yog dab tsi?
Peak inverse voltage (PIV) yog qhov siab tshaj plaws qhov hluav taws xob muaj peev xwm hla lub diode thaum nws tau thim rov qab. Tam sim no qhov hluav taws xob hla qhov tsis ua haujlwm diode D2 yog qhov sib npaug ntawm qhov hluav taws xob hla qis ib nrab ntawm kev hloov pauv thib ob thiab qhov hluav taws xob hla qhov tsis kam thauj khoom RL
Qhov sib piv sib piv rau tus menyuam CPR yog dab tsi?
6.7 Kev Sib Koom Hauv Siab thiab Lub Qhov Ncauj Ib tus neeg cawm siav siv lub tshuab nqus pa-rau-qhov sib piv ntawm 30: 2. Rau 2-cawm tus menyuam mos thiab menyuam CPR, ib tus kws khomob yuav tsum ua lub hauv siab thaum lwm tus ua kom cov hlab pa qhib thiab ua pa tawm ntawm qhov sib piv ntawm 15: 2
Cov cai tseem ceeb ntawm Txoj Cai Txiav Txim Tus Kheej Tus Kheej Tus Kheej li Psda yog dab tsi?
PSDA xav kom txhua lub chaw saib xyuas kev noj qab haus huv (tsev kho mob, chaw saib xyuas mus sij hawm ntev, thiab cov koom haum saib xyuas kev noj qab haus huv hauv tsev) tau txais Medicare thiab Medicaid them nyiaj rov qab kom paub txog lub neej nyob thiab lub hwj chim ntawm kws lij choj rau kev saib xyuas kev noj qab haus huv raws li kev qhia ua ntej
Dab tsi yog tsib tus qauv tseem ceeb ntawm kev tswj tus kheej tus kab mob ntev?
Feem ntau ntawm cov kev tshawb fawb yog nyob hauv Asmeskas. Tsib tus qauv mob hnyav suav nrog Tus Qauv Kho Mob Ntev (CCM), Txhim Kho Kev Kho Mob Mob Ntev (ICIC), thiab Kev Tsim Kho Tshiab rau Kev Kho Mob Ntev (ICCC), Qauv Stanford (SM) thiab Zej Zog raws Kev Hloov Tus Qauv (CBTM). CCM yog tus qauv kawm ntau tshaj plaws
Ob qho piv txwv piv txwv yog dab tsi?
Hauv nws qhov kev txhais dav tshaj plaws, ua piv txwv tuaj yeem suav nrog cov qauv tsis nyob. Cov ntsiab lus tshwj xeeb masquerade thiab mimesis qee zaum siv thaum cov qauv tsis muaj sia. Piv txwv li, cov tsiaj xws li paj mantises, cov paj ntoo cog, cov paj ntoo thiab kab zauv kab npauj npaim kab ntsig zoo li cov ntoo, tawv ntoo, nplooj, nplooj noog poob lossis paj ntoo
