Abstract:

Based on differential geometry, a novel dynamic characteristic analysis method for a bidirectional matrix converter is proposed. The internal dynamics and stability of the system and dynamic characteristic are achieved by the different outputs. And thus the parameters of the control strategies are given. The results show that the method can prove the efficiency of the analysis of the circuits. In consideration of the output parameters of the circuit, a control scheme based on input-output linearization theory is proposed. The validity of the analysis law with excellent steady-state and dynamic characteristics is verified by the simulation results.
