Tag nrho cov topologies xav tau ceev hloov hluav taws xob hloov pauv. Lub boost theem thiab tag nrho-bridge conversion theem yuav tsum ceev switching diodes. Tsis tas li ntawd, cov keyboards optimized rau tsawg zaus (100Hz) hloov dua siab tshiab kuj tseem pab tau rau cov topologies. Rau ib qho tshwj xeeb silicon thev naus laus zis, cov keyboards optimized rau kev hloov ceev ceev muaj kev ua haujlwm ntau dua li cov keyboards optimized rau tsawg zaus hloov daim ntawv thov.

Lub boost theem feem ntau yog tsim los ua ib tug nruam tam sim no converter. Raws li tus naj npawb ntawm hnub ci modules nyob rau hauv array siv los ntawm inverter, xaiv seb puas siv 600V lossis 1200V li. Ob txoj kev xaiv rau lub zog hloov pauv yog MOSFET thiab IGBT. Feem ntau hais lus, MOSFET tuaj yeem ua haujlwm ntawm qhov hloov pauv ntau dua li IGBT. Tsis tas li ntawd, kev cuam tshuam ntawm lub cev diode yuav tsum nco ntsoov: tsis muaj teeb meem nyob rau hauv cov ntaub ntawv ntawm lub zog theem, vim hais tias lub cev diode tsis ua nyob rau hauv ib txwm ua hauj lwm hom. Lub conduction poob ntawm MOSFET tuaj yeem suav tau raws li kev ua haujlwm tsis zoo RDS (ON). Rau ib tug muab MOSFET series, qhov no yog proportional rau qhov zoo tuag cheeb tsam. Thaum lub ntsuas hluav taws xob hloov pauv ntawm 600V mus rau 1200V, qhov kev poob ntawm MOSFET yuav nce ntau. Yog li ntawd, txawm tias qhov ntsuas RDS (ON) sib npaug, 1200V MOSFET tsis muaj lossis tus nqi siab dhau.
