In order to measure the output power of double dielectric barrier discharge,a detection circuit is set up inside the AC high voltage power supply,and the output parameters of the power supply are tested by using an oscilloscope.The measured Q-V Lissajous figure area was calculated by using the method of origin software and parallelogram,and the discharge power of the double dielectric barrier reactor was obtained.The results show that the Q-V Lissajous figure can be obtained by using the built-in detection circuit,and the result obtained by using the method of parallelogram is similar and the calculation method is simple and reliable.Power output efficiency is more than 55%,which provided a favorable reference for the power output research of double dielectric barrier discharge.
