Experiment recording video of MPPM module for high drive performance

Instructions for Experimental Recording Video

A microsecond pulse power module (MPPM) conversion system with high performance is proposed in this manuscript (TPEL-Reg-2023-05-1116) for low-voltage lithium battery-powered portable DBD plasma source devices. High performance is not only reflected in the proposed MPPM has excellent driving performance for small DBD electrode discharge, but also reflected in the optimization of the system volume parameters. This video recording aims to better demonstrate the driving advantages of the proposed MPPM module on a human-touchable SDBD plasma source portable device. The proposed MPPM module can reduce the temperature of the SDBD electrode from 66 ° C to 60 ° C during the same running time.

This video records two experimental working conditions respectively. The given input voltage, and pulse parameters are completely consistent, and the running time is about 3 minutes. The influence of the RDD branch in the proposed MPPM circuit on the discharge characteristics of the SDBD electrode is compared. The details are as follows:

• The first part is that the MPPM module does not add an RDD branch. After running for 3 minutes, the maximum temperature of the SDBD electrode reaches 66℃. Moreover, due to the time limitation of video recording, the temperature of the SDBD electrode is still rising.

• The second part is the MPPM module added RDD branch, after 3 minutes of operation, the maximum temperature of the SDBD electrode is less than 60℃, and its temperature rise is very slow, almost has reached the thermal equilibrium temperature.

This experimental recording video can well prove that the proposed MPPM has good driving performance.
