研究目的
Investigating the development and application of a current divider based on current comparator techniques for precise and accurate splitting of alternating current (ac) in two parts.
研究成果
The current comparator based current divider simplifies the measurement tasks of several ac quantities by digital sampling techniques, offering highly accurate current ratios with potential applications in ac metrology.
研究不足
The current divider does not provide galvanic isolation between the split currents, and the accuracy can be affected by winding impedance mismatches without electronic compensation.
