For the RS-485 interface, the SM712 asymmetric voltage design (-7V to 12V) can effectively suppress common mode interference.

2. Kev tiv thaiv kev hloov hluav taws xob
Nyob rau ntawm DC sab ntawm photovoltaic inverters, nws yog ib qho tsim nyog los daws cov teeb meem hluav taws xob thiab kev khiav hauj lwm overvoltages. SMBJ15CA TVS diode (rov qab tua hluav taws xob 15V, ncov mem tes fais fab 600W) los ntawm Shilanxin Semiconductor yog ntim rau hauv SMB / DO-214AA, nrog lub thermal tsis kam qis li 10℃/ W, uas tuaj yeem xa tawm lub zog hloov pauv sai thiab tiv thaiv IGBT tom ntej module los ntawm voltage surges.

3. Zog Cia Converter (PCS) Kev Tiv Thaiv
PCS input chaw nres nkoj yuav tsum tau tiv thaiv kev cuam tshuam kev sib raug zoo thiab kev hloov pauv ntawm qhov hluav taws xob ntawm kab sib chaws. Zhixin Microelectronics 'SiC SBD thiab LEM siab-cov cuab yeej tam sim no ua haujlwm ua ke kom ua tiav kev hloov pauv ntawm 99.2% hauv siab- zaus topology, thiab tau dhau TÜ V Rheinland ntawv pov thawj kom ua tau raws li IEC 62109 tus qauv kev nyab xeeb.
