Abstract
The optimization design method of three-phase grid connected inverter efficiency was discussed.The loss model of switches and inductor was set up,the efficiency of three-phase inverter was expressed as a function of the parameters of switching frequency,DC bus voltage,inductor core size,air gap length of inductance and winding turns and size,combined with the requirements of the grid current THD and inductance temperature design index,the inverter efficiency optimization problem was converted into nonlinear constrained single objective optimization problem. Based on the optimization method,an optimized design method of three-phase grid-connected inverter efficiency was obtained,and preliminary experimental verification was carried out.关键词
