This paper USES the extension describing function method for two-way arch bridge LLC resonant con-verter is mathematical modeling, the small signal linear dynamic model is established. Based on the finished design of compensating network. Finally closed loop network to make use of Matlab software simulation analysis, the experimen-tal results show that by the mathematical model for the design of closed loop control system has good dynamic and steady state performance, proved by extending the describing function method can be more accurate to two-way bridge LLC resonant converter for mathematical modeling analysis.
