| Abstract: | The research on impedance characteristics of power modules is very important in the stability estimation for cascaded power systems. In this paper, the input and output impedances of the voltage mode controlled full bridge converter under CCM operation are clearly analyzed. The influences of the loop gain on the impedance characteristics are discussed and presented in the paper. The experimental results show that the proposed research process could be used to analyze the impedance characteristics of other power modules. |
