In On the basis of analyzing the bidirectional converter topology, and working principle, based on thea feedforward decoupling based double loop feedforward control loop control strategy has been adopted to achieve the automatic switch in different modes of rectifier inverter automatically switches as so to to achieve a energy bi-direction flow.achieve the purpose of energy flow in both directions. This method hasThere is not any no static error tracking input current, and the harmonic pollution is low as well as, the power factor advantagesis high..
