I. Technical Challenges & Objectives
Traditional current transformers (CTs) suffer from large size, AC-only measurement limitations, and magnetic saturation risks. Addressing the needs of modern compact electronic systems (e.g., battery management, servo drives, compact inverters) for space savings, lightweight design, DC detection, and high-frequency response, this solution offers a miniaturized, high-density, AC/DC-compatible Hall-effect current sensing approach.
