| Affiliation: | By using transfer parameter matrix T of LCL immittance converter, the input-output characteristics fuction of system at resonance are deduced. The performances of system influenced by the variation of source frequency and element parameter are discussed in detail. For different loads and frequencies the efficiency equation, output current curve and efficiency curve are given by theory analysis and MATLAB model building. Circuit simulation and analysis results prove that the LCL immittance converter can keep well constant-current characteristic and well robustness, the maximum efficiency during energy transfer is 98.02%. |
