Si loo xaqiijiyo hawlgalka xawaaraha isbeddelaya ee matoorka, tignoolajiyada inverter-ka ayaa si weyn loogu isticmaalaa matoorka aan qarxin. Qalab ahaan, inverter-ku wuxuu u rogi karaa korontada soo noqnoqota ee korontada (50Hz ama 60Hz) noocyo kala duwan oo koronto AC ah, si loo gaaro hawlgalka xawaaraha isbeddelaya ee matoorka. Qalabku wuxuu ka kooban yahay wareeg kontarool si loo xakameeyo wareegga ugu weyn; Wareegga Rectifier-ka si loogu beddelo hadda beddelan ee hadda toosan; Wareegga dhexe ee DC waxaa loo isticmaalaa in lagu simo oo lagu shaandheeyo wax soo saarka wareegga rectifier-ka; Wareegga Inverter-ka, oo loo isticmaalo in lagu beddelo hadda toosan ee hadda beddelan. Beddelayaasha soo noqnoqda qaarkood ee u baahan inay qabtaan hawlo badan, waxaa sidoo kale lagama maarmaan ah in lagu qalabeeyo CPU si loo xisaabiyo wareegga iyo wareegga u dhigma. Iyadoo la beddelayo soo noqnoqoshada sahayda korontada ee wareegga stator-ka ee matoorka, nidaaminta xawaaraha soo noqnoqda ee isbeddelaya waxay xaqiijin kartaa ujeeddada nidaaminta xawaaraha.
Inverter Sida laga soo xigtay hababka kala soocidda ee kala duwan, waxaa loo qaybin karaa nooca danab-beddelka iyo nooca hadda jira, inverter-ka xakamaynta PAM, inverter-ka xakamaynta PWM iyo inverter-ka xakamaynta PWM ee soo noqnoqda sare, inverter-ka xakamaynta V/f, inverter-ka xakamaynta soo noqnoqda ee simbiriirixan iyo inverter-ka xakamaynta vector-ka, inverter-ka guud, inverter-ka gaarka ah ee waxqabadka sare leh, inverter-ka soo noqnoqda sare leh, inverter-ka hal-waji iyo inverter-ka saddex-waji ah, iwm.
Beddelaha soo noqnoqda, VVVF waxaa loola jeedaa isbeddelka danabka iyo soo noqnoqoshada, halka CVCF ay tilmaamayso danab joogto ah iyo soo noqnoqoshada joogtada ah. Korontada AC-ga ee loo isticmaalo waddamada adduunka oo dhan, ha ahaato guryaha ama warshadaha, danabka iyo soo noqnoqoshada badanaa waa 400V/50Hz ama 200V/60Hz (50Hz). Qalabka korontadaas u beddela koronto beddela koronto ama isbeddel soo noqnoqoshada AC-ga waxaa loo yaqaan "beddelaha soo noqnoqda". Si loo soo saaro danabyo iyo soo noqnoqosho isbeddelaya, qalabku marka hore wuxuu u baahan yahay inuu beddelo hadda beddela koronto toos ah (DC).
Beddelaha soo noqnoqda waxaa loo isticmaalaa in lagu xakameeyo matoorka wuxuuna beddeli karaa labadaba danabka iyo soo noqnoqoshada. Sida ku cad muujinta xawaaraha matoorka AC, xawaaraha n wuxuu la mid yahay soo noqnoqoshada f, xawaaraha matoorkana waa la hagaajin karaa ilaa inta soo noqnoqoshada f la beddelayo. Sidaa darteed, beddelaha soo noqnoqoshada wuxuu ku qancaa nidaaminta xawaaraha isagoo beddelaya soo noqnoqoshada korontada matoorka, taas oo ah hab nidaamin hufnaan sare leh iyo hab nidaamin xawaare sare leh.
Horumarinta qalabka wax lagu beddelo ee soo noqnoqda, habab kala duwan oo xakameyn ah ayaa soo ifbaxay, oo ay ku jiraan:
Habka xakamaynta ee isbeddelka ballaca garaaca wadnaha ee sinusoidal (SPWM), halkaas oo 1U/f=C;
Habka xakamaynta vector-ka booska danabka (SVPWM);
Habka xakamaynta Vektorka (VC);
Habka xakamaynta wareegga tooska ah (DTC);
Isgoyska Matrix - qaabka xakamaynta isgoyska, iwm.
Kor, waxaa lagu sharraxayaa adeegsiga hal-abuurka leh ee inverter-ka ee matoorka aan qarxin. Iyada oo loo marayo tignoolajiyada inverter-ka, xawaaraha matoorka waxaa loo hagaajin karaa si dabacsan, taasoo keenaysa hufnaan sare iyo xalal awoodeed oo heer sare ah oo loogu talagalay warshadaha.
