Professional inverter inogadzira mikana isingaperi.

Nhanganyaya yeInverter

Inverter chinhu chemagetsi chinoshandura ikozvino alternating ikozvino yakananga ikozvino, inonyanya kushandiswa kupa simba kune mutoro.Inverter chishandiso chinoshandura DC voltage sosi kuita AC voltage sosi.Inogona kushandiswa mumicrocomputer kana single-chip microcomputer system pamwe nechiratidzo chekugadzira michina.

Invertersinogona kukamurwa kuita imwe-chikamu, matatu-chikamu uye yakazara-bhiriji inverters zvinoenderana nedanho resimba.Chikamu chimwe chete uye matatu-chikamu inverters anoumbwa neshanduko, mafirita uye LC mafirita, uye iyo yakabuda waveform ndeye sine wave;yakazara-bhiriji inverters inoumbwa nerectifier sefa wedunhu, Schottky diode (PWM) dunhu uye dhiraivha redunhu, uye inobuda waveform is square wave.

Invertersinogona kuiswa mumhando nhatu: yakagadziriswa pa-off type, yakafa-zone control type (sine wave nzira) uye switch control type (square wave nzira).Nekuvandudzwa kwesimba remagetsi tekinoroji, ma inverters anoshandiswa zvakanyanya munzvimbo dzakasiyana siyana.

Basic concepts

Inverter isimba remagetsi mudziyo unoshandura yakananga ikozvino kuita alternating current.Iyo inverter ine rectifier sefa wedunhu, Schottky diode (SOK) dunhu uye dhiraivha dhiraivha.

Iyo inverter inogona kukamurwa kuita inoshanda inverter uye passive inverter, passive inverter, inozivikanwawo seye inverter wedunhu kana voltage regulator wedunhu, kazhinji nedanho rekuisa, yepakati nhanho (LC) sefa, yekubuda nhanho (rectifier), nezvimwewo, uye iyo inoshanda inverter ndiyo yekuisa voltage chiratidzo chekushandura kuti uwane yakagadzikana DC voltage.

Iyo passive inverter kazhinji ine muripo capacitor mune rectifier zambuko, nepo inoshanda inverter ine sefa inductor mune rectifier zambuko.

Inverter redunhu rine zvakanakira saizi diki, huremu huremu, hukuru hwepamusoro uye zvichingodaro.Icho chikamu chakakosha chemarudzi ese emagetsi emagetsi emagetsi.

Classification

Zvinoenderana neiyo topology ye inverter inogona kukamurwa kuita: yakazara-bhiriji inverter, push-pull inverter.

Inogona kukamurwa kuva PWM (pulse width modulation) inverter, SPWM (quadrature signal modulation) inverter uye SVPWM (space voltage vector modulation) inverter.

Zvinoenderana nedhiraivha yedunhu redhisheni inogona kukamurwa kuita: hafu-bhiriji, push-dhonza mhando.

Zvinoenderana nemhando yemhando, inogona kukamurwa kuita imwe-chikamu inverter magetsi, matatu-chikamu inverter magetsi, DC inoshandura, inoshanda sefa inverter magetsi, nezvimwe.

Zvinoenderana neiyo control mode inogona kukamurwa kuita: yazvino modhi uye voltage mode.

Munda Wekushandisa

Inverters anoshandiswa zvakanyanya mumaindasitiri otomatiki, mauto ehondo, aerospace uye mamwe minda.Semuyenzaniso, muindasitiri otomatiki, reactive magetsi ekubhadhara maturusi anonyanya kushandiswa mumasisitimu emagetsi anogona kugadzirisa yakakwira-voltage magetsi, kuvandudza kugadzirwa kwekugadzira, kuchengetedza simba remagetsi uye kupa yakagadzikana magetsi ekugadzira maindasitiri;mukukurukurirana, reactive simba muripo wemagetsi zvishandiso zvinogona kushandiswa kugadzirisa voltage ye low-voltage masisitimu kuti idzikame mukati mehumwe hunoenderana uye kuona kutaurirana kureba;mukufambisa, anogona kushandiswa mumotokari injini kutanga system uye mota yekuchaja bhatiri system;mumidziyo yehondo, inogona kushandiswa mumagetsi uye otomatiki kudzora sisitimu yezvombo;mune zvemuchadenga, zvinogona kushandiswa muinjini yendege kutanga magetsi uye bhatiri yekuchaja magetsi.
