Gukoresha Inverter mu buryo bushya muri Moteri idaturika

Kugira ngo moteri ikore umuvuduko uhindagurika, ikoranabuhanga rya inverter rikoreshwa cyane muri moteri idaturika. Nk'igikoresho, inverter ishobora guhindura ingufu z'amashanyarazi (50Hz cyangwa 60Hz) mo ingufu zitandukanye za AC, kugira ngo moteri ikore umuvuduko uhindagurika. Igikoresho kirimo circuit igenzura circuit nyamukuru; Rectifier circuit yo guhindura alternating current mu direct current; DC intermediate circuit ikoreshwa mu koroshya no kuyungurura umusaruro wa rectifier circuit; Inverter circuit, ikoreshwa mu guhindura direct current mu alternating current. Muri zimwe mu mashini zihindura frequency zikenera gukora ibikorwa byinshi, ni ngombwa kandi kugira CPU yo kubara torque na circuit ijyanye nayo. Mu guhindura frequency y'amashanyarazi ya stator winding ya moteri, regulation variable frequency speed regulation ishobora kugera ku ntego yo kugenzura umuvuduko.

Inverter Dukurikije uburyo butandukanye bwo gushyira mu byiciro, ishobora kugabanywamo inverter yo mu bwoko bwa voltage na inverter yo mu bwoko bwa current, inverter yo kugenzura PAM, inverter yo kugenzura PWM na inverter yo kugenzura PWM yo mu bwoko bwa carrier, inverter yo kugenzura V/f, inverter yo kugenzura frequency ya slip na inverter yo kugenzura vector, inverter rusange, inverter yihariye ifite imikorere myiza, inverter yo kugenzura frequency nyinshi, inverter imwe na inverter y’icyiciro cya gatatu, nibindi.

Mu ihindura ry’amakuru (frequency converter), VVVF yerekeza ku guhinduka kwa voltage na frequency, mu gihe CVCF yerekeza ku guhinduka kwa voltage na frequency ihoraho. Mu ikoreshwa ry’amashanyarazi ya AC rikoreshwa mu bihugu hirya no hino ku isi, haba mu ngo cyangwa mu nganda, voltage na frequency akenshi ni 400V/50Hz cyangwa 200V/60Hz (50Hz). Igikoresho gihindura umuriro nk’uwo mu buryo bwa voltage cyangwa frequency variable power supply cyitwa "frequency converter". Kugira ngo hakorwe voltage na frequencies zihindagurika, igikoresho kigomba kubanza guhindura alternating current muri direct current (DC).

Imashini ihindura frequency ikoreshwa mu kugenzura moteri kandi ishobora guhindura voltage na frequency. Dukurikije uko umuvuduko wa moteri ya AC uhagaze, umuvuduko n ujyanye na frequency f, kandi umuvuduko wa moteri ushobora guhindurwa igihe cyose frequency f ihindutse. Kubwibyo, iyi mashini ihindura frequency igenzura umuvuduko ihindura frequency y'amashanyarazi ya moteri, ari nabyo bigena umuvuduko mwinshi kandi imikorere myiza.

Mu iterambere rya za frequencies, habayeho uburyo butandukanye bwo kugenzura, burimo:

Uburyo bwo kugenzura ubugari bwa sinusoidal pulse modulation (SPWM), aho 1U/f=C;

Uburyo bwo kugenzura amashanyarazi (SVPWM);

Uburyo bwo kugenzura vektori (VC);

Uburyo bwo kugenzura torque mu buryo butaziguye (DTC);

Ihuriro rya matrix - uburyo bwo kugenzura ihuriro, nibindi.

Haruguru, harasobanurwa uburyo bushya bwo gukoresha inverter muri moteri idaturika. Binyuze mu ikoranabuhanga rya inverter, umuvuduko wa moteri ushobora guhindurwa mu buryo bworoshye, bigatanga umusaruro mwiza kandi ufite ingufu nyinshi mu rwego rw'inganda.
