STGAP2HS Galvanically Isolated 4 Woyendetsa Galimoto Yokha

STMicroelectronics 'woyendetsa pagalimoto m'modzi amadzipatula pakati pa chipata choyendetsa ndi magetsi ochepa

STMicroelectronics 'STGAP2HS ndi driver imodzi yapa chipata yomwe imadzipatula pakati pa njira yoyendetsera chipata ndi low-voltage control ndi mawonekedwe a circry. Woyendetsa chipata amadziwika ndi kuthekera kwa 4 A ndi njanji kuchokera ku njanji, ndikupangitsa kuti chipangizocho chikhale choyeneranso kugwiritsa ntchito mphamvu zapakatikati komanso zamphamvu monga kutembenuza mphamvu ndi oyendetsa magalimoto oyendetsa mafomu. Chipangizocho chimapezeka m'mitundu iwiri. Kapangidwe kake ndi zikhomo zolekanitsidwa zimalola ogwiritsa ntchito kuti azimitsa okha kuyatsa ndi kutseka pogwiritsa ntchito zotsutsana ndi zipata. Kukhazikitsa komwe kumakhala ndi pini imodzi yotulutsa komanso ntchito ya Miller CLAMP imalepheretsa ma spikes azipata mukamayenda mwachangu mu matayala a theka-mlatho. Masinthidwe onsewa amapereka kusinthasintha kwakukulu komanso ndalama zakuchepetsa zakunja. Chipangizocho chimagwirizanitsa ntchito za UVLO ndi zotchinga zotsekera kuti zithandizire pakupanga kachitidwe kodalirika kwambiri. Zikhomo wapawiri athandizira kulola kusankha chizindikiro polarity kulamulira ndi kukhazikitsa kwa HW popiringidzana chitetezo kupewa conduction mtanda vuto la wonongeka. Zowonjezera pakuchedwetsa kwakuchulukitsa ndizochepera 75 ns, zomwe zimapereka kulondola kwamphamvu kwa PWM. Njira yoyimirira ilipo kuti muchepetse kugwiritsidwa ntchito kwamagetsi.
