Ikon Gudun Fan Mai Hankali: Tsarin Fitowa na Pulse Width Modulation (PWM) yana sarrafa saurin sanyin fan. Wannan keɓantaccen fitowar mai tarawa yana daidaita saurin fan bisa tsarin sake zagayowar aikin PWM, yana ba da damar daidaitawa tsakanin aikin sanyaya da yawan amo/makamashi.
Serial Board Identification: A 1024-bit serial memory guntu yana adana bayanan hukumar da bita, yana barin tsarin ya gano allon ta atomatik don kulawa da bincike.
3. Ƙa'idar Aiki
Aikin hukumar yana zagaye da ainihin EPLD ɗin sa, sarrafawa da amsa sigina daga babban iko da filin.
Ƙarfafawa/Sake saitin Farawa: Bayan an kunna wutar lantarki, babban CPU yana daidaita BICL's EPLD ta hanyar bayanan P2 da bas ɗin adireshi, yana ƙayyade yanayin aikinsa (IGBT ko SCR).
Gudun Siginar Aiki na al'ada:
