Ugbu a stabilizer: designation, nkọwa atụmatụ

Modern nwoke bụ mgbe niile gbara ya gburugburu a nnukwu ọnụ ọgụgụ nke ọkụ na ngwá, ma anụ ụlọ na ulo oru. O siri ike iche n'echiche ndụ anyị enweghị ihe ọ bụla eletriki ngwaọrụ, ha na-eji nwayọọ bara n'ụlọ. Ọbụna anyị akpa a ga-enwe mgbe nile a ole na ole ndị dị otú ahụ na ngwaọrụ. All nke a technology maka ya anụ ọrụ na-achọ a na-aga n'ihu ọkọnọ nke ọkụ eletrik. Mgbe ọduọ na mains voltaji na ugbu a bụ ọtụtụ ihe na-akpata ọdịda nke ngwaọrụ.

Iji hụ na àgwà ọkọnọ nke oru ngwá kacha mma iji a ugbu a stabilizer. Ọ ga-enwe ike chefuo maka netwọk fluctuations na ogologo ọrụ ndụ.

ugbu a stabilizer - a ngwaọrụ nke na-akpaghị aka na-ekwusi n'ji ugbu a na a gaghị agara nkenke. Ọ ụgwọ ugboro nke ugbu a surges ke netwọk, mgbanwe nke ibu ike na ihere okpomọkụ. Ka ihe atụ, na-amụba n'ike gwusia site ngwaọrụ, ga-agbanwe ọsọ ọsọ ugbu a, na-eme ndị voltaji dobe na isi iyi na-eguzogide ma wiring eguzogide. The ukwuu uru nke esịtidem eguzogide, ndị ọzọ voltaji ga-agbanwe na-amụba ibu ugbu a.

Ụgwọ ugbu a stabilizer bụ a ngwaọrụ akpaka akara, nke ihe mejupụtara a yinye ọjọọ nzaghachi. Stabilization a na-enweta site na-agbanwe afọ nke ukpụhọde so, na ikpe nke ikpughe na nzaghachi usu. Nke a oke a na-akpọ ọrụ nke mmepụta ugbu a. Regulatory pụtara compensatory ugbu stabilizers bụ: na-aga n'ihu, pulsed na weere.

Isi parameters:

1. Nọsi'ike akpata uru nke input voltaji:

_St.t K = (ΔU _Rin / ΔI _H) * (m _H / U _Bx), ebe

M _n, ΔI _n - ugbu a bara uru na increment uru nke ugbu a na ibu.

_St.t ọnụọgụ K gbakọọ na mgbe nile ibu eguzogide.

2. The ọnụọgụ nke stabilization bụrụ na nke na-eguzogide mgbanwe:

K _{R H} = (ΔR _n / R _n) * (m _H / ΔI _H ) = R _i / R _{H, nke}

R _H , ΔR _n - na increment nke ndị na-eguzogide nke ibu-eguzogide;

r _i - uru nke esịtidem eguzogide stabilizer.

The ọnụọgụ K _{R H} na gbakọọ na a mgbe nile input voltaji.

3. The uru nke okpomọkụ ọnụọgụ stabilizer: γ = ΔI _n / Δt _env.

Iji ike parameters stabilizers akọ arụmọrụ: η = P _O / P _Rin.

A nnọọ n'ọtụtụ ebe na-agbasa stabilizer ugbu FET, mgbe a na-adịghị circuited n'ọnụ ụzọ ámá na isi iyi, karị, U = 0 _agbụ. The transistor dị otú ahụ a circuit ejikọrọ na usoro na ibu eguzogide. The nrutu ihe na ogologo ibu mmepụta e ji mara nke transistor chọpụta ugbu a bara uru na ndị kasị nta na ndị kasị ibu uru nke input voltaji. Dị otú ahụ na a ibu ugbu a circuit dịgasị ubé na a ịrịba mgbanwe na input voltaji.

Ịmafe regulator ya e ji mara dị ugbu a nke transistor - na njikwa na ịmafe ala. Nke a na-eme ka o kwe omume ka iwelie arụmọrụ nke ngwaọrụ.

Ụdị ngwaọrụ dabere na mmejuputa iwu nke ike unit nwere ike kewara abụọ na ụdị: a usoro njikọ nke a trotul na a transistor; na a Oghere Usoro njikọ na a yiri inductor regulator transistor njikọ.
