摘要

薄膜梳状热变换器广泛用于获取交流电流或电压的均方值以及测量各种形式的电信号的功率。目前还没有关于这些热变换器在高频上运行的可靠数据。本文建立了热电堆分流效应对薄膜梳状变换器结构中高频电流分布影响的解析模型。给出了所考虑的薄膜梳状热转换器的结构。在这种结构中，热电堆的热结被放置在加热器附近。热热结的这种配置允许热转换器的工作频率值增加到500至600 MHz。

Thin-film comb thermal converter: influence of shunt effect of thermopile on high-frequency current distribution

Thin-film comb thermal converters are widely used for obtaining mean square values of alternating current or voltage and for measuring a power of electrical signals having various forms. At the present time reliable data about the operation of these thermal converters on high-frequencies are absent. In this paper the analytical model allowing one to determine the influence of the shunt effect of the thermopile on the high frequency current distribution in the structure of the thin-film comb thermal converter is presented. The structure of the thin-film comb thermal converter under consideration is shown. In this structure hot thermojunctions of the thermopile are placed near the heater. Such disposition of the hot thermojunctions permits the value of the operation frequency of the thermal converter to be increased to 500 to 600 MHz.
