Based on Negative Magnetic Reluctance Structure of LLC Converter
The LLC converter has been widely used in the new energy field due to its advantages of soft switching in full load range, low EMI, high efficiency and high power density. In order to increase the output voltage range of LLC converter, this paper proposes a frequency-dependent passive variable inductor based on negative magnetic reluctance structure (NMRS), and the frequency-gain curve of LLC converter is designed by the variation curve of inductor. Based on FEM simulation, the inductor variation curve is designed and substituted into the frequency-gain curve of LLC for calculation, and the feasibility of the method is verified experimentally.
