Gukoresha udushya twa Inverter muri moteri iturika

Kugirango tumenye imikorere yihuta ya moteri, tekinoroji ya inverter ikoreshwa cyane muri moteri idashobora guturika.Nkigikoresho, inverter irashobora guhindura amashanyarazi yumuriro (50Hz cyangwa 60Hz) muburyo butandukanye bwo gutanga amashanyarazi ya AC, kugirango ugere kubikorwa byihuta bya moteri.Igikoresho kirimo uruziga rwo kugenzura imiyoboro nyamukuru;Inzira ikosora kugirango ihindure imiyoboro ihindagurika;Inzira ya DC intera ikoreshwa muguhuza no gushungura ibisohoka byumuzunguruko;Inverter umuzenguruko, ikoreshwa muguhindura imiyoboro itaziguye.Mubice bimwe bihindura imirongo ikeneye gukora ibikorwa byinshi, birakenewe kandi gushyirwaho na CPU yo kubara torque hamwe nizunguruka.Muguhindura amashanyarazi yumurongo wa stator ihindagurika ya moteri, ihinduka ryihuta ryihuta rishobora kumenya intego yo kugenzura umuvuduko.

Inverter Ukurikije uburyo butandukanye bwo gutondekanya ibyiciro, birashobora kugabanywa muburyo bwa voltage inverter hamwe nubwoko bwubu, inverter ya PAM, inverter ya PWM hamwe nu mutwaro mwinshi wa PWM igenzura, V / f igenzura, iniverisite yo kugenzura inshuro nyinshi, inverter, imikorere yimikorere idasanzwe, inverter yumurongo mwinshi, icyiciro kimwe inverter nicyiciro cya gatatu, nibindi.

Muguhindura inshuro, VVVF bivuga guhindura voltage na frequency, mugihe CVCF bivuga voltage ihoraho hamwe numurongo uhoraho.Mu mashanyarazi ya AC akoreshwa mu bihugu byo ku isi, haba mu ngo cyangwa mu nganda, voltage na frequency ni 400V / 50Hz cyangwa 200V / 60Hz (50Hz).Igikoresho gihindura amashanyarazi nkaya mumashanyarazi cyangwa amashanyarazi ahinduka amashanyarazi yitwa "guhinduranya ibintu".Kugirango ubyare amashanyarazi ahindagurika hamwe na frequence, igikoresho gikeneye kubanza guhindura imiyoboro ihinduranya yerekeza kuri DC (DC).

Guhindura inshuro zikoreshwa mugucunga moteri kandi irashobora guhindura voltage na frequency.Ukurikije umuvuduko wa moteri ya AC, umuvuduko n ugereranije numurongo f, kandi umuvuduko wa moteri urashobora guhinduka mugihe cyose f yahinduwe.Kubwibyo, guhinduranya imirongo imenya umuvuduko muguhindura moteri yumuriro wa moteri, nuburyo bwiza kandi bwihuse bwo kugenzura imikorere.

Mugutezimbere abahindura imirongo, uburyo butandukanye bwo kugenzura bwagiye buhinduka, harimo:

Sinusoidal pulse ubugari modulation (SPWM) uburyo bwo kugenzura, aho 1U / f = C;

Umwanya wa voltage umuyaga (SVPWM) uburyo bwo kugenzura;

Kugenzura Vector (VC) uburyo;

Uburyo butaziguye bwo kugenzura (DTC);

Guhuza Matrix - uburyo bwo kugenzura amasangano, nibindi.

Hejuru, uburyo bushya bwo gukoresha inverter muri moteri idashobora guturika byasobanuwe.Binyuze mu buhanga bwa inverter, umuvuduko wa moteri urashobora guhindurwa byoroshye, bikazana imikorere ihanitse kandi ikemura ibibazo byinshi mumashanyarazi.
