Abstract

The DC/DC power conversion of micro-inverter system has the characteristics of low input voltage,large input current,wide input voltage range and high output voltage.So DC/DC converter is required to have the characteristics of high step-up,high efficiency and wide input adaption by the micro-inverter system.LLC resonant converter perfectly satisfies these requirements.For this reason,digitally-controlled step-up LLC resonant converter applied in micro-inverter system was studied in this paper.The design method of the resonant tank based on optimal magnetizing inductance was proposed and digitally-controlled realization of LLC resonant converter was presented in detail using a kind of DSP chip named TMS320F28335.Finally,a three-hundred-watt prototype was build.The full load efficiency is 96.6% under rated input voltage together with 96.8% maximum value,and the full load efficiency reach above 96% under whole input range.
