1.前言交流电压的测量,没有如直流(DC)电压标准那样的参考源。为了精确测量交流电压和电流,采用热电压变换器是很必要的。本文描述现行方法及基于晶体管和薄膜电阻的新型热变换器技术。测量交流信号可用多种方法,最通用的方 1. Introduction AC voltage measurement, there is no reference source such as the DC voltage standard. In order to accurately measure the AC voltage and current, the use of thermal voltage converter is necessary. This article describes the current approach and new thermal converter technology based on transistors and thin film resistors. There are many ways to measure AC signals, the most common one
