Txoj kev siv multimeter rau kev kuaj xyuas lub zog inverter module
Thaum lub hwj chim module raug kuaj (tshem tawm ntawm daim phiaj hluav taws xob), lub collector thiab emitter ntawm rau lub diodes ntawm tus choj rectifier thiab rau IGBT raj ntawm cov zis choj tuaj yeem ntsuas rau pem hauv ntej thiab rov qab siv lub pointer multimeter R × l los txiav txim. seb lawv puas tau tawg. Table 1 thiab Table 2 yog cov txiaj ntsig kev ntsuas ib txwm, txwv tsis pub muaj cov khoom tawg sab hauv. Ntsuas qhov tsis kam (tsav lub teeb liab input davhlau ya nyob twg) ntawm lub rooj vag thiab emitter ntawm rau IGBT transistors siv lub pointer multimeter Bx1k. Yog tias muaj qhov sib txawv, nws qhia txog kev puas tsuaj rau lub voj voog tsav lossis IGBT transistor. Cov kev ntsuas saum toj no tsuas yog ntsuas qhov kev puas tsuaj ntawm cov hlab IGBT. Tsis muaj qhov qhib Circuit Court puas tuaj yeem kuaj pom. Tom qab tshem tawm lub hwj chim module los ntawm lub rooj tsav xwm Circuit Court, txhua lub IGBT raj tuaj yeem ntsuas ntxiv siv txoj hauv kev qhia hauv daim duab 1, qhov twg lub koob ntawm sab laug qhia tias tsis yog conductivity. Lub koob ntawm sab xis qhia txog conductivity. Yog tias nws tsis tuaj yeem qhib thiab kaw, lub raj puas lawm.
Qauv ntawm zaus converter fais fab module:
Lub ntim sab hauv ntawm lub zaus hloov hluav taws xob module muaj ib-theem lossis peb-theem choj rectifier Circuit Court tsim los ntawm diodes, thiab lwm qhov peb-theem choj tso tawm hluav taws xob tsim los ntawm rau IGBT transistors (insulated gate bipolar transistors) thiab rau damping diodes siv. hauv kev sib txuas.
P1 yog lub davhlau ya nyob twg zoo ntawm +300V rectifier tso zis, thiab N1 yog qhov tsis zoo ntawm cov zis rectifier. Ob lub pins no tau txuas nrog sab nraud rau lub lim dej electrolytic capacitor, thiab txuas nrog P2 thiab N2 los ntawm kev sib nrig sib inductance coils P1 thiab N1, raws li, muab lub zog rau tus choj tso zis uas muaj rau IGBT raj.
Cov khoom siv ntawm peb lub IGBT transistors nyob rau sab sauv ib nrab ntawm tus choj peb-theem tso zis txuas nrog lub davhlau ya nyob twg zoo ntawm lub zog hluav taws xob, thiab cov emitters yog U, V, thiab W peb-theem tso zis terminals. Cov emitters thiab rooj vag ntawm peb lub transistors tsim cov input terminals GU-U, GV-V, thiab GW-W rau lub teeb liab tsav tsheb ntawm lub sab sauv ib nrab choj. Cov neeg sau ntawm peb IGBT transistors nyob rau hauv qis ib nrab choj ntawm peb-theem tso zis choj txuas nrog U, V, thiab W, thiab cov emitters txuas nrog rau qhov tsis zoo ntawm cov khoom siv hluav taws xob. Lub rooj vag ntawm peb lub transistors thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob tsim cov tswv yim terminals GX, GY, thiab GZ rau lub teeb liab tsav tsheb ntawm tus choj qis dua. B yog lub braking tswj davhlau ya nyob twg.
Tsis muaj braking circuit hauv no module. TH yog qhov tso zis davhlau ya nyob twg tiv thaiv los ntawm lub tshuab thermistor sab hauv. Txawm hais tias cov pins thiab cov cim ntawm lub rooj tsav xwm hauv Circuit Court ntawm lwm cov qauv ntawm universal zaus converter fais fab modules txawv, nws tsis yooj yim los txheeb xyuas cov haujlwm tseem ceeb ntawm tus pin. Cov khoom lag luam siab txais yuav cov khoom siv hluav taws xob ntse, uas suav nrog kev tsav tsheb thiab cov braking circuits sab hauv, nrog rau ntau tus pins.
Lub hwj chim module ntawm ib zaus converter, raws li lub npe qhia, yog hais txog kev sib xyaw ntawm cov hluav taws xob hluav taws xob thiab hluav taws xob cov khoom siv nyob rau hauv zaus converter raws li tej yam dej num thiab ces encapsulated rau hauv ib lub module. Lub zaus converter nws tus kheej yog tsim los ntawm chav tswj thiab lub zog module. Nyob rau hauv dav dav, lub hwj chim module ntawm ib tug zaus converter yog tsim los ntawm integrating lub plhaub sab nraud thiab sab nraud electrode terminals kom txo tau tus naj npawb ntawm cov Cheebtsam thiab cov xov hlau inductance.
