4000w DC rau Ac Off Grid Inverter

GI series: 4000w dc rau ac tawm daim phiaj inverter

German physicist Heinrich Hertz nrhiav tau nyob rau hauv 1887 hais tias ci ntsa iab ultraviolet lub teeb ntawm electrodes yuav pab tsim sparks ntau. Qhov no yog qhov tshwm sim uas tsim los ntawm cov nyhuv photoelectric. Physicists suav nrog Joseph Thomson thiab Philip Leonard tau ua ntau txoj kev tshawb fawb thiab kev sim kev tshawb fawb txog cov nyhuv photoelectric. Xyoo 1905, Albert Einstein tau luam tawm ib daim ntawv piav qhia txog ntau yam kev sim cov ntaub ntawv ntawm cov nyhuv photoelectric. Einstein tau sib cav hais tias cov kab teeb ci muaj ib pawg ntawm discrete quanta (tam sim no hu ua photons), tsis yog qhov hloov pauv tas li. Yog tias qhov zaus ntawm photon ntau dua li qee qhov kev txwv ntau zaus, photon muaj lub zog txaus los ua kom cov electrons ntawm cov hlau saum npoo dim, uas ua rau cov nyhuv photoelectric. Qhov kev tshawb pom tseem ceeb no qhib qhov rooj rau quantum physics.

Xyoo 1901, Guglielmo Marconi tau xa xov tooj cua los ntawm Askiv, hla Atlantic, mus rau Canada. Tsib xyoos tom qab, "txiv ntawm xov tooj cua" Lee DeForest tau tsim lub tshuab nqus tsev triode. Qhov kev tsim khoom loj no tau txhawb nqa lub hnub nyoog hluav taws xob mus rau tom ntej sai heev uas xov tooj cua thiab xov tooj nyob deb nroog tsis yog npau suav nyob deb lawm. Los ntawm xyoo 1940 thiab 1950s, cov khoom siv hauv lub xeev tau pib tshwm sim ntau thiab ntau zaus, ua rau muaj kev poob qis sai ntawm cov tshuab nqus tsev vacuum thiab kev nce ntawm semiconductor technology. Lub transistor tau tsim nyob rau hauv 1947 los ntawm ib pab neeg ntawm William Shockley, John Bardeen, thiab Walter Bratton ntawm Bell Labs. Qhov no yog ib qho tseem ceeb tshaj plaws inventions ntawm lub xyoo pua nees nkaum, thiab cov khoom siv hluav taws xob feem ntau yuav tsum tau siv cov transistors. Jack Kilby nws tus kheej tau tsim cov kev sib koom ua ke hauv xyoo 1958 thiab Robert Noyce hauv xyoo 1959. Niaj hnub no, ntau cov khoom siv hluav taws xob xws li transistors, diodes, resistors, capacitors, thiab lwm yam tuaj yeem sib sau ua ke hauv ib qho kev sib koom ua ke.
