Simulation of LCC resonant converter applied to;glow discharge cleaning power supply

Under the constant current requirement of the power supply after the gas breakdown in the glow discharge cleaning system, a new scheme of LCC resonant converter is proposed to improve the scheme of glow discharge cleaning power supply and increase the reserve of power supply scheme. The software tool is used to select the parameter range, assist to understand the topological characteristics and verify the scheme. The influence of the main parameter quality factor QL and the series and parallel capacitance ratio A in the LCC transfer function on the circuit gain and resonant device stress is analyzed, and the reasonable value is designed. Based on the designed value, MATLAB simulation indicates that the closed-loop output of the power supply reaches the rated value, and the LCC topology meets the requirements of glow discharge cleaning power supply parameters. The current normalization curve of LCC resonant converter shows good constant current characteristics and is suitable for designing as a current source. (authors)
