我们报告的发展薄膜多结热转换器的测量交流电流高达10 A，而不依赖于并联电流分流。为这些器件选择的材料和设计经过优化，可在广泛的输入电平和频率范围内提供高精度。在用铜-金加热器制成的10 A芯片上的初步测量表明，从10 Hz到100 kHz，其AC-DC差几乎为零，并且AC-DC差与输入电流电平无关。
We report on the development of thin-film multijunction thermal converters for the measurement of AC currents up to 10 A without relying on parallel current shunts. The materials and designs chosen for these devices have been optimized to provide high accuracy over a wide range of input levels and frequencies. Preliminary measurements on a 10-A chip made with a copper-gold heater indicate that its ac-dc difference is nearly zero from 10 Hz to 100 kHz, and that the AC-DC difference is independent of input current level.
