　　The classical PID control algorithm is extensively used in inverter， but its control precision should be improved， Being aimed at this problem， double loop control algorithm in inverter’s control is researched in this paper. The composition of inverter using double loop control algorithm is given， and the parameters’ of voltage and current are designed. Simulation model of inverter by using double loop control algorithm is constructed .By the way of simulation， the choose of control parameters are tested and verified， and it’s proved that the inverter has good output performances when double loop control algorithm is used.
