Weghachite imewe sekit igbochi ugbu a

Reverse current bụ mgbe voltaji na mmepụta nke usoro dị elu karịa voltaji na ntinye, na-eme ka ọ dị ugbu a na-agafe na usoro na ntụgharị ntụgharị.

Isi mmalite:

1. diode ahụ na-aga n'ihu mgbe a na-eji MOSFET maka ngwa ngbanwe ibu.

2. Mwepu na mberede na ntinye voltaji mgbe ike na-apụ na usoro.

Oge ndị a ga-ekwesịrị ịtụle ihe mgbochi azụ ugbu a:

1. mgbe ike multiplexed ọkọnọ na-achịkwa MOS

2. ORing njikwa.ORing yiri ike multiplexing, ma e wezụga na kama ịhọrọ ọkụ eletrik iji mee ka usoro ahụ dị ike, a na-eji voltaji kachasị elu mgbe niile iji mee ka usoro ahụ dị ike.

3. ngwa ngwa voltaji na-adaba n'oge ọnwụ ike, karịsịa mgbe mmepụta mmepụta dị ukwuu karịa ike ntinye.

Ihe egwu:

1. reverse ugbu a nwere ike mebie esịtidem circuitry na ike ọkọnọ

2. tụgharịa spikes dị ugbu a nwekwara ike imebi eriri na njikọ

3. diode ahụ nke MOS na-ebili na oriri ike na ọbụna nwere ike imebi

Ụzọ kachasị mma:

1. Jiri diodes

Diodes, karịsịa Schottky diodes, bụ nke a na-echebe site n'okike pụọ na polarity nke dị ugbu a na nke na-atụgharị, mana ha dị oke ọnụ, nwere nnukwu mmiri mmiri na-atụgharị, na-achọkwa ikpo ọkụ.

2. Jiri azụ-na-azụ MOS

Enwere ike igbochi ntụziaka abụọ ahụ, mana ọ na-enwe nnukwu mpaghara osisi, nnukwu ihe mgbochi conduction, ọnụ ahịa dị elu.

Na ọnụ ọgụgụ na-esonụ, njikwa transistor njikwa, onye nchịkọta ya dị ala, ihe abụọ PMOS na-eduzi, mgbe transistor kwụsịrị, ọ bụrụ na mmepụta dị elu karịa ntinye, n'akụkụ aka nri nke MOS body diode conduction, nke mere na ọkwa D bụ. elu, na-eme ka ọkwa G dị elu, akụkụ aka ekpe nke MOS ahụ diode adịghị agafe, na n'otu oge ahụ, n'ihi MOS nke VSG maka ahụ diode voltaji ọdịda adịghị eru voltaji ọnụ ụzọ, ya mere, MOS abụọ mechiri, nke gbochiri mmepụta na ntinye ugbu a.Nke a na-egbochi ihe dị ugbu a site na mmepụta gaa na ntinye.

3. Agbanwe MOS

Reverse MOS nwere ike igbochi mmepụta na ntinye nke a na-atụgharị ugbu a, ma mwepu bụ na a na-enwe mgbe nile a ahu diode ụzọ si ntinye na mmepụta, na ọ bụghị smart zuru ezu, mgbe mmepụta dị ukwuu karịa ntinye, enweghị ike ịtụgharị. gbanyụọ MOS, mana ọ dịkwa mkpa ịgbakwunye sekit ntụnyere voltaji, yabụ enwere ezigbo diode mechara.

4. Ibu ngbanwe

5. Multiplexing

Multiplexing: ịhọrọ otu n'ime ihe ntinye abụọ ma ọ bụ karịa n'etiti ha iji mee ka otu mmepụta dị ike.

6. Ideal Diode

Enwere ihe mgbaru ọsọ abụọ n'ịmepụta diode dị mma, otu bụ ịmegharị Schottky na nke ọzọ bụ na a ghaghị inwe sekit ntụnyere ntinye-mpụta iji gbanyụọ ya na ntụgharị.
