Umkhwa wophuhliso lwemarike ye-voltage ephezulu yokuqhubela phambili

Ngophuhliso olukhawulezayo lwetekhnoloji ye-elektroniki yamandla anamhlanje kunye neteknoloji yolawulo lwekhompyuter, uguqulo lobuchwepheshe bokuqhuba umbane luye lwakhuthazwa.Ulawulo lwesantya se-Ac endaweni yolawulo lwesantya se-DC, ulawulo lwedijithali lwekhompyutha endaweni yolawulo lwe-analog lube yindlela yophuhliso.Ulawulo lwesantya sokuguqulwa kweemoto ze-Ac yeyona ndlela iphambili yokugcina amandla, ukuphucula inkqubo yemveliso, ukuphucula umgangatho wemveliso, kunye nokuphucula imeko yokusebenza.Ummiselo wesantya esiguqukayongobuchule bayo obuphezulu, amandla aphezulu, kunye nolawulo olubalaseleyo lwesantya kunye nokusebenza kweziqhoboshi kunye nezinye iingenelo ezininzi zithathwa njengowona mthetho uthembisayo wesantya.

Eyangaphambilii-inverter ene-voltage ephezulu, eyakhiwe nge-thyristor rectifier, inverter ye-thyristor kunye nezinye izixhobo, ineentsilelo ezininzi, i-harmonics enkulu, kwaye inefuthe kwigridi yamandla kunye nemoto.Kwiminyaka yakutshanje, ezinye izixhobo ezitsha ziye zaphuhliswa eziza kutshintsha le meko, njenge-IGBT, IGCT, SGCT kunye nokunye.Uguqulo lwamandla ombane aphezulu oluqulunqwe ngabo lunokusebenza okugqwesileyo kwaye luyakwazi ukuqonda i-PWM inverter kunye nokulungiswa kwe-PWM.Akunjalo kuphela i-harmonics encinci, kodwa kunye namandla amandla aphuculwe kakhulu

Itekhnoloji yokulawula isantya sokuguqulwa kwesantya se-Ac yindibaniselwano yombane owomeleleyo kunye nobuthathaka, itekhnoloji yokudibanisa oomatshini kunye nombane, kungekuphela nje ukujongana nokuguqulwa kwamandla amakhulu (ukulungiswa, inverter), kodwa kunye nokujongana nokuqokelela kolwazi, ukuguqulwa kunye nokuhanjiswa. , ngoko kufuneka ihlulwe ibe ngamandla kwaye ilawule iindawo ezimbini.Owokuqala kufuneka asombulule iingxaki zobugcisa ezinxulumene nombane ophezulu kunye nophezulu lwangoku, kwaye lo mva kufuneka usombulule iingxaki zesoftware kunye ne-hardware.Ke ngoko, itekhnoloji yolawulo lwesantya soguqulo lwamandla ombane aphezulu nayo iya kuphuhliswa kule miba mibini, ukusebenza kwayo okuphambili kukuba:

(1) IUkuguquguquka kwamandla ombane aphezuluiya kuphuhlisa kwicala lamandla aphezulu, i-miniaturization kunye nekhaphukhaphu.

(2) Iphezului-voltage variable frequency driveiya kuphuhlisa kumacala amabini: isixhobo esithe ngqo samandla ombane aphezulu kunye ne-multiple superposition (uthotho lwesixhobo kunye nothotho lweeyunithi).

(3) Izixhobo ezitsha zesemiconductor yamandla ombane aphezulu kunye nomsinga ongaphezulu ziya kusetyenziswai-high voltage variable frequency drive

(3) Kule nqanaba, i-IGBT, i-IGCT, i-SGCT iya kudlala indima enkulu, i-SCR, i-GTO iya kuphuma kwi-market inverter market.

(4) Ukusetyenziswa kokulawulwa kwe-vector, ukulawulwa kwe-flux kunye neteknoloji yokulawula i-torque ngokuthe ngqo ngaphandle kwenzwa yesantya iya kukhula.

(5) Ukuqonda ngokupheleleyo idijithali kunye ne-automation: i-parameter self-setting technology;Itekhnoloji yokuzenzela inkqubo;Itekhnoloji yokuzibona ngempazamo.

(6) Ukusetyenziswa kwe-32-bit ye-MCU, i-DSP kunye nezixhobo ze-ASIC, ukufezekisa ukuchaneka okuphezulu kunye ne-multi-function inverter.
