Rusa na'urorin samar da wutar lantarki masu ƙarancin ƙarfi na YMIN: Daga fa'idodin sigina zuwa aikin gaske, Yadda ake "sanyaya da inganta inganci" a Tsarin Samar da Wutar Lantarki?

Gabatarwa

Ya ku injiniyoyin samar da wutar lantarki, shin kun taɓa fuskantar matsala da yawan ripple da zafi da capacitors ke yi yayin da kuke gyara kurakurai a cikin samfuran? Musamman a cikin neman ƙarfin lantarki mai yawa a yau, ƙarfin ESR da ƙarfin ripple na capacitors sun zama shinge marasa ganuwa waɗanda ke ƙayyade nasara ko gazawar ƙira. Wannan labarin zai ɗauki jerin VPX/VPT na YMIN a matsayin misali don zurfin nazarin fasaha, yana nuna yadda yake magance waɗannan wuraren ciwo tare da bayanai na zahiri.

Misali, idan aka yi amfani da caja mai sauri ta 65W 2C2A GaN, yana buƙatar ya kula da mitoci masu canzawa har zuwa ɗaruruwan kHz a cikin sarari mai iyaka. Idan aka yi amfani da capacitors na yau da kullun (ESR kusan 40mΩ), ba za a yi watsi da asarar su a manyan mitoci ba. Mun lura cewa a ƙarƙashin cikakken fitarwa, zafin jiki na ainihin irin waɗannan capacitors na iya wuce 85℃, wanda ba wai kawai yana haifar da haɗarin aminci na zafi ba, har ma yana haifar da lalacewar capacitance da ƙaruwar ESR saboda yawan zafin jiki, wanda ke haifar da tambayoyi game da aminci na dogon lokaci.

Babban matsalar tana cikin ESR. Asarar wutar lantarki P_loss = I_rms² × ESR. Lokacin da mitar sauyawa ta tashi zuwa 100kHz, amsawar capacitive (Xc) tana raguwa sosai, kuma ESR ta zama babban ɓangaren impedance. Idan aka ɗauki capacitor mai ESR na 40mΩ yana ɗauke da wutar ripple 2A a matsayin misali, asarar tantanin halitta ɗaya tana da yawa har zuwa 0.16W. A cikin ƙaramin sarari, wannan zafi yana da matuƙar wahalar wargajewa.Maganin YMINyana rage ESR zuwa 20mΩ, yana rage asarar zuwa 0.08W a ƙarƙashin irin wannan yanayi, yana rage rabin samar da zafi kai tsaye da kuma magance matsalar hauhawar zafin jiki ta asali.
