The Power Measurement of DBD Ozone Reactor Based on the Quasi-Synchronous Algorithm

Ozone production with Dielectric Barrier Discharge (DBD) is a typical example of the applications of low temperature plasma technology. The most critical process is to inject power into the DBD reactor. But because of the characteristic of DBD reactor, the voltage and current of power supply are distorted severely and make the measurement of input power for DBD ozone reactor even hard. This paper, based on Quasi-synchronous sampling algorithm, establishes the input power measurement systems of DBD ozone reactor and achieves the online real-time monitoring input power of DBD ozone reactor. The experimental results prove that the relative errors of more than 95% is less than0.3% between power measurement system based on Quasi-synchronous sampling algorithm and the measurement data with oscilloscope.
