Optimal design for LCL-SRC type

الملخص EN

The LCL Series Resonant Converter (LCL-SRC) type offer nearly load- independent output voltage under some operating conditions.

By this way the output voltage can be regulated against a wide load and line variations with a small variation of switching frequency.

In this paper a simple method for optimization of LCL-SRC is presented.

This method takes the stored energy as a theoretical index to obtain the minimal size of the converter inductors L1 and L2 which contribute significantly to the converter size and weight.

The R0-method for the analysis of resonant converter is discussed.

This method was found fairly accurate for operation above resonant frequency
