Pono ka lio maikaʻi i kahi noho maikaʻi! No ka hoʻohana piha ʻana i nā pono o nā polokalamu SiC, pono nō hoʻi e hoʻohui i ka ʻōnaehana kaapuni me nā capacitors kūpono. Mai ka mana hoʻokele nui i nā kaʻa uila a hiki i nā hiʻohiʻona ikehu hou e like me nā photovoltaic inverters, ke hele mālie nei nā capacitors kiʻiʻoniʻoni, a makemake nui ka mākeke i nā huahana kiʻekiʻe.
I kēia mau lā, ua hoʻokumu ʻo Shanghai Yongming Electronic Co., Ltd. i nā capacitors kākoʻo kiʻiʻoniʻoni DC, nona nā pōmaikaʻi maikaʻi ʻehā i kūpono iā lākou no nā IGBT ʻehiku o Infineon. Kōkua pū lākou i ka hoʻoponopono ʻana i nā pilikia o ke kūpaʻa, ka hilinaʻi, ka miniaturization, a me ke kumukūʻai i nā ʻōnaehana SiC.
Loaʻa i nā capacitors kiʻiʻoniʻoni kokoke i 90% ke komo ʻana i nā noi hoʻokele nui. No ke aha e pono ai ʻo SiC a me IGBT iā lākou?
I nā makahiki i hala iho nei, me ka hoʻomohala wikiwiki ʻana o nā ʻoihana ikehu hou e like me ka mālama ʻana i ka ikehu, ka hoʻopiʻi ʻana, a me nā kaʻa uila (EVs), ua piʻi wikiwiki ka noi no nā capacitors DC-Link. ʻO ka waiho wale ʻana, hana nā capacitors DC-Link ma ke ʻano he buffers i nā kaʻapuni, e hoʻomoʻi i nā kahe pulse kiʻekiʻe mai ka hopena o ke kaʻa a hoʻomaʻemaʻe i ka uila kaʻa, pēlā e pale ai i nā hoʻololi ʻana o IGBT a me SiC MOSFET mai nā kahawai pulse kiʻekiʻe a me nā hopena uila transient.
ʻO ka maʻamau, hoʻohana ʻia nā capacitor electrolytic alumini i nā noi kākoʻo DC. Eia nō naʻe, me ka piʻi ʻana o ka volta kaʻa o nā kaʻa ikehu hou mai 400V a 800V a me nā ʻōnaehana photovoltaic e neʻe ana i 1500V a hiki i 2000V, ke piʻi nui nei ke koi no nā capacitors kiʻiʻoniʻoni.
Hōʻike ka ʻikepili i ka makahiki 2022, ʻo ka mana i hoʻokomo ʻia o nā mea hoʻohuli uila e pili ana i nā capacitors kiʻiʻoniʻoni DC-Link i hōʻea i 5.1117 miliona mau ʻāpana, helu ʻia no 88.7% o ka nui o ka mana o nā mana uila. Ke alakaʻi nei i nā hui hoʻokele uila e like me Fudi Power, Tesla, Inovance Technology, Nidec, a me Wiran Power e hoʻohana i nā capacitors kiʻiʻoniʻoni DC-Link i kā lākou mau mea hoʻohuli hoʻokele, me ka lakene hiki i ka 82.9%. Hōʻike kēia ua hoʻololi nā capacitor kiʻiʻoniʻoni i nā capacitor electrolytic ma ke ʻano he kumu nui i ka mākeke kaʻa uila.
ʻO kēia no ka mea ʻoi aku ka nui o ke kūpaʻa uila o nā capacitors electrolytic alumini ma kahi o 630V. I nā volta kiʻekiʻe a me nā noi mana kiʻekiʻe ma luna o 700V, pono e hoʻopili ʻia nā capacitor electrolytic he nui i ka moʻo a me ka like e hoʻokō i nā koi hoʻohana, e lawe mai ana i ka nalowale o ka ikehu, ke kumukūʻai BOM, a me nā pilikia hilinaʻi.
Ua hōʻike ʻia kahi pepa noiʻi mai ke Kulanui o Malaysia e hoʻohana mau ʻia nā capacitors electrolytic i ka loulou DC o nā mea hoʻohuli hapa-alahaka IGBT silicon, akā hiki ke piʻi i ka volta ma muli o ke kiʻekiʻe kiʻekiʻe e like me ke kūpaʻa series (ESR) o nā capacitors electrolytic. Ke hoʻohālikelike ʻia i nā ʻōnaehana IGBT i hoʻokumu ʻia i ke silika, ʻoi aku ka kiʻekiʻe o ka SiC MOSFET i nā alapine hoʻololi kiʻekiʻe, e hopena i nā amplitudes kiʻekiʻe kiʻekiʻe ma ka loulou DC o nā mea hoʻohuli hapalua alahaka. Hiki i kēia ke alakaʻi i ka hoʻohaʻahaʻa hana a i ʻole ka pōʻino, no ka mea, ʻo 4kHz wale nō ka resonant frequency o nā capacitor electrolytic, ʻaʻole lawa e komo i ka ripple o nā mea hoʻohuli SiC MOSFET.
No laila, i nā noi DC me nā koi hilinaʻi kiʻekiʻe, e like me nā mea hoʻohuli uila a me nā inverters photovoltaic, koho ʻia nā capacitor kiʻiʻoniʻoni. Ke hoʻohālikelike ʻia me nā capacitors electrolytic aluminika, ʻo kā lākou hana pono e loaʻa i ke kūpaʻa uila kiʻekiʻe, haʻahaʻa ESR, ʻaʻohe polarity, ʻoi aku ka paʻa o ka hana, a ʻoi aku ka lōʻihi o ke ola ʻana, e hiki ai i kahi hoʻolālā ʻōnaehana hilinaʻi me ke kūpaʻa ripple ikaika.
Eia kekahi, me ka hoʻohana ʻana i nā capacitors kiʻiʻoniʻoni i loko o ka ʻōnaehana hiki ke hoʻohana pinepine i nā pono kiʻekiʻe, haʻahaʻa haʻahaʻa o ka SiC MOSFET, e hōʻemi nui i ka nui a me ke kaumaha o nā mea passive (inductors, transformers, capacitors) i ka ʻōnaehana. Wahi a Wolfspeed noiʻi, pono ka 10kW silicon-based IGBT inverter 22 alumini electrolytic capacitors, ʻoiai he 40kW SiC inverter pono wale nō 8 film capacitors, e hōʻemi nui ana i ka wahi PCB.
Hoʻokuʻu ʻo YMIN i nā Capacitors Kiʻiʻoniʻoni Hou me ʻEhā mau Pōmaikaʻi Nui e kākoʻo i ka ʻoihana ʻenehana hou
No ka hoʻoponopono ʻana i nā koi mākeke wikiwiki, ua hoʻokumu ʻo YMIN i ka MDP a me MDR moʻo o nā capacitors kiʻi kākoʻo DC. Ke hoʻohana nei i nā kaʻina hana kiʻekiʻe a me nā mea kiʻekiʻe kiʻekiʻe, ua kūpono kēia mau capacitors me nā koi hana o SiC MOSFET a me nā IGBT i hoʻokumu ʻia i ke silicon mai nā alakaʻi semiconductor mana honua e like me Infineon.
He mau hi'ohi'ona kaulana ko YMIN's MDP a me MDR series film capacitors: low equivalent series resistance (ESR), high rate voltage, leakage current, a me ke ki'eki'e o ka wela.
ʻO ka mea mua, hōʻike ʻia nā capacitors kiʻiʻoniʻoni a YMIN i kahi hoʻolālā ESR haʻahaʻa, e hōʻemi pono ana i ke koʻikoʻi o ka uila i ka wā o ka hoʻololi ʻana o SiC MOSFET a me nā IGBT i hoʻokumu ʻia i ke silika, a laila e hōʻemi ana i nā poho capacitor a hoʻomaikaʻi i ka pono o ka ʻōnaehana holoʻokoʻa. Hoʻohui ʻia, loaʻa i kēia mau capacitors ka volta helu kiʻekiʻe, hiki ke kū i nā kūlana kiʻekiʻe a me ka hōʻoia ʻana i ka hana ʻōnaehana paʻa.
Hāʻawi ka MDP a me MDR o nā capacitors kiʻiʻoniʻoni YMIN i nā pae capacitance o 5uF-150uF a me 50uF-3000uF, a me nā pae uila o 350V-1500V a me 350V-2200V, kēlā me kēia.
ʻO ka lua, ʻo nā capacitors kiʻiʻoniʻoni hou loa a YMIN he haʻahaʻa leakage o kēia manawa a ʻoi aku ka paʻa o ka mahana. I ka hihia o nā ʻōnaehana uila uila, ka mea maʻamau i ka mana kiʻekiʻe, hiki i ka hopena wela ke hoʻopilikia nui i ke ola a me ka hilinaʻi o nā capacitors kiʻiʻoniʻoni. No ka hoʻoponopono ʻana i kēia, ʻo ka MDP a me MDR series mai YMIN e hoʻokomo i nā mea kiʻekiʻe a me nā ʻenehana hana kiʻekiʻe e hoʻolālā i kahi hoʻolālā wela maikaʻi no nā capacitors. Mālama kēia i ka hana paʻa ʻoiai ma nā wahi wela kiʻekiʻe, e pale ana i ka hōʻemi ʻana o ka waiwai capacitor ma muli o ka piʻi ʻana o ka wela. Eia kekahi, ʻoi aku ka lōʻihi o kēia mau capacitors, e hāʻawi ana i ke kākoʻo hilinaʻi no nā ʻōnaehana uila mana.
ʻO ke kolu, ʻo ka MDP a me ka MDR series capacitors mai YMIN e hōʻike ana i kahi liʻiliʻi liʻiliʻi a me ka mana kiʻekiʻe. No ka laʻana, i nā ʻōnaehana uila uila 800V, ʻo ke ʻano ka hoʻohana ʻana i nā polokalamu SiC e hōʻemi i ka nui o nā capacitors a me nā ʻāpana passive ʻē aʻe, no laila e hāpai i ka miniaturization o nā mana uila. Ua hoʻohana ʻo YMIN i ka ʻenehana hana kiʻiʻoniʻoni hou, ʻaʻole ia e hoʻonui wale i ka hoʻohui ʻana o ka ʻōnaehana holoʻokoʻa a me ka maikaʻi akā e hōʻemi ana i ka nui o ka ʻōnaehana a me ke kaumaha, e hoʻonui ai i ka lawe a me ka maʻalahi o nā mea hana.
ʻO ka holoʻokoʻa, hāʻawi ka YMIN's DC-Link film capacitor series i kahi 30% hoʻomaikaʻi i ka dv/dt hiki ke kū a me ka piʻi ʻana o 30% i ke ola i hoʻohālikelike ʻia me nā capacitors kiʻiʻoniʻoni ʻē aʻe ma ka mākeke. ʻAʻole wale kēia e hāʻawi i ka hilinaʻi maikaʻi loa no nā kaʻa SiC / IGBT akā hāʻawi pū kekahi i ka maikaʻi o ke kumukūʻai, e lanakila ana i nā kumu kūʻai i ka hoʻohana ākea o nā capacitors kiʻiʻoniʻoni.
Ma ke ʻano he paionia ʻoihana, ua komo nui ʻo YMIN i ke kahua capacitor no nā makahiki he 20. Ua hoʻohana paʻa ʻia kāna capacitors kiʻekiʻe i nā kula kiʻekiʻe e like me ka OBC ma luna o ka moku, nā puʻupuʻu e hoʻouka ai i ka ikehu hou, photovoltaic inverters, a me nā robots ʻoihana no nā makahiki he nui. ʻO kēia hanauna hou o nā huahana capacitor kiʻiʻoniʻoni e hoʻonā i nā pilikia like ʻole i ka hoʻokele kaʻina hana capacitor kiʻiʻoniʻoni a me nā lako, ua hoʻopau i ka hōʻoia hilinaʻi me nā ʻoihana alakaʻi honua, a ua hoʻokō i ka noi nui, e hōʻike ana i ka hilinaʻi o ka huahana i nā mea kūʻai aku. I ka wā e hiki mai ana, e hoʻohana ʻo YMIN i kāna hōʻiliʻili ʻenehana no ka wā lōʻihi e kākoʻo i ka hoʻomohala wikiwiki ʻana o ka ʻoihana ikehu hou me nā huahana capacitor kiʻekiʻe a me ke kumu kūʻai.
