Umphumphu Wamphamvu (PE)

Zogawana zazikuluzo, zimatchedwa PI, ndikutsimikizira ngati magetsi ndi gwero lamphamvu lamphamvu ndi komwe akupita kukwaniritsa zofunikira. Umphumphu wamagetsi umakhala ndi vuto lalikulu kwambiri mu kapangidwe kake kothamanga kwambiri.

Mulingo wa kukhulupirika kwamphamvu kumaphatikizapo chip Pakati pawo, umphumphu wa magetsi pagawo la madera akuyenera kukwaniritsa zofunikira zitatu zotsatirazi:

1. Pangani magetsi ku chip pini yaying'ono kuposa kutanthauzira (mwachitsanzo, cholakwika pakati pa magetsi ndi 1V ndi ochepera + /50mv);

2.

3, Chepetsani zosokoneza electromagnetic (EMI) ndikusamalira Elekitom Electromagnetic (EMC): PROME) ndiye wochititsa kwambiri (PDN) ndiye wochititsa kwambiri kwambiri pabwalo lamadera, motero ndi njira yosavuta kwambiri yopatsirana ndikulandila phokoso.

Vuto Lokhala Ndi Mphamvu

Mphamvu yopatsa vuto kukhulupirika imachitika makamaka chifukwa cha mapangidwe opanda pake a capakorlict, mphamvu yoyipa, ndege yoyipa ya magetsi / nthaka yopanda tanthauzo. Kudzera mu kulinganiza kwa umphumphu, mavutowa adapezeka, Mavuto Omwe Amphumphu amagetsi adathetsedwa ndi njira zotsatirazi:

Kusanthula kwamphamvu kwamphamvu

Posanthula umphumphulika wa Entery, mitundu yayikulu yovutayi ikuphatikiza kusanthula kwa DC Voldage, kusanthula kwamphamvu ndi kusanthula kwa phokoso. Kusanthula kwa DC Voldage kumaphatikizapo kusanthula kwamiyala yovuta ndi ndege pa PCB ndipo itha kugwiritsidwa ntchito kuti mudziwe za voliyumu yomwe idzatayika chifukwa chokana mkuwa.

Ikuwonetsa kuchuluka kwa kuchuluka ndi ma graph otentha a "malo otentha" mu pi / matenthedwe

Kusanthula kusanthula kumayendetsa kusintha kwa mtengo, mtundu, ndi kuchuluka kwa ma carmitors omwe amagwiritsidwa ntchito pa PDN. Chifukwa chake, ndikofunikira kuphatikiza kuphatikizira kwa parasitic ndikulimbana ndi ntchito ya Capacitor.

Mtundu wa kusanthula kwa phokoso kumatha kusiyanasiyana. Amatha kuphatikizira phokoso kuchokera ku zikhomo za IC Power yomwe imafalitsa mozungulira madera ndipo imatha kulamulidwa ndi mavacorling. Posanthula kwa phokoso, ndizotheka kufufuza momwe phokoso limaphatikizira kuchokera ku bowo lina, ndipo ndizotheka kupenda phokoso lokhazikika.
