Evaluation of the Peltier current lead (PCL) system at the half-wave-rectified current (HWRC) mode was evaluated numerically, and compared with the results of Conventional current lead (CCL) and PCL at DC mode. Characteristics of the PCL system at HWRC mode were evaluated with reduction of the Seebeck coefficient of thermoelectric element (TE). Calculation results show that the heat leak is reduced by introducing the PCL although the conducting current has the large ripple. However, reduction of the heat leak was small in this calculation. The reason of small reduction is due to the gas cooling. Comparing to the effect of gas cooling and the Peltier effect, it was found that these effects have two same characteristics. They are 1) Both effects are the effect and heat transport from the lower temperature side to higher temperature side and depend on the temperature difference. 2) Both effects increase with current conduction. The former is due to the increase of current, and the latter is due to the increase of the heat leak by conducting the current.
