There are several designs and techniques for measuring the ac voltage. The ac-dc thermal transfer standards represent the common method for measuring the ac voltage accurately in terms of the dc voltage. The single junction thermal converter (SJTVC) is widely used as thermal transfer standard. It is to be noted that the SJTVC is mainly an electric resistor (heater) whose temperature is sensed by a standard thermocouple. This device has an input which is ac voltage and an output signal represented by the output voltage of the thermocouple. This thermal converter suffers from many drawbacks...
