| Abstract: | In this paper, the design and construction of a high-voltage high-frequency serial resonant bridge inverter endowed with a fast resonant frequency following capability, using the digital phase locked loop (DPLL) technique, is described. The main characteristics of this inverter are: high voltage (10?kV), high frequency (94.3?kHz), and low losses in the commutation devices. This inverter is used for the excitation of a dielectric barrier discharge cell (DBDC) for cold plasma generation. The system has been applied in hazardous organic compound degradation. In particular, benzene has been degraded to the order of 99.85%, according to measurements obtained by gas chromatography. |
