I. Technicae Difficultates & Objectiva
Transformatores currentis (CTs) traditionales magni sunt in magnitudine, limitati ad mensurationes AC solum, et periculis saturationis magneticae obnoxii. Ad satisfaciendum necessitatibus systematum electronicorum modernorum compactorum (exempli gratia, gestionis batteriarum, motorum servo, converterum compactarum) pro conservatione spatii, designo levi, detectione DC, et responsione altae frequentiae, haec solutio offert approchum miniaturizatum, alta densitate, AC/DC-compatibilem, sensum Hall-effect currentis.
II. Nucleus Technologiae: Sensor Hall Flux-Balance Clausus + Integratio ASIC
- Magneto Circuitum & Sensum Nuclei Minuti
- Architectura Flux-Balance Clausa: Chip Hall microsiliconicus imbutus intra nucleum flux-concentricum annulare specialiter designatum (materialis alta permeabilitate).
- Principium Cancellationis Campi Magnetici:
- Campum magneticum a currente primario generatum detectum a chip Hall.
- Circuitus feedback amplificatus secundarium coil inducit ad generandum campum contrariam, ad statum "zero-flux" real-time assequendum.
- Current feedback precise reflectit currentem primarium, eliminans nonlinearietatem et drift thermalem in designis apertis inherentes.
- Signalis Processus Altissime Integratus
- Integratio ASIC Dedicata:
- Amplificatio signalis Hall parvonoise
- Circuitus cancellationis offset dynamicus
- Algorithmus compensationis thermalis altissimae precisionis (mitigans drift thermale silicis)
- Filtratio low-pass adjustabilis (typica: 100–250 kHz)
- Voltus reference integrata et driver output
- Structura Designi Ultra-Compacta
- Nucleus Minutus: Circuitus magneticus optimizatus cum foraminibus tam parvis ut Ø5mm (foramen standard transversal) vel foraminibus rectangularibus superfacie montatis.
- Montatura SMD/Transversalis:
- Pacchetti superfacie montati (exempli gratia, SMD-8) pro assemblatione PCB directa, altitudo ≤ 10mm.
- Designus transversalis (structura sine pedibus) permittit routing conductoris directus per foramen nucleus, habilitans installationem galvanice isolatam.
