Embodiment Construction
[0031] The present invention will be further described below in conjunction with specific examples.
[0032] like figure 1 As shown, the working mode analysis method of the complex power electronic converter provided in this embodiment includes the following steps:
[0033] 1) Draw each component in the power electronic converter into the tree diagram according to the sequence of current flow, wherein, according to the sequence of current flow, it means starting from the power supply, drawing all the components in the circuit into the tree diagram in sequence, in When drawing a tree diagram, it is assumed that each component in the circuit has a specific one-way conductivity, that is, regardless of the current flow direction of the actual component, it is set to start from the positive pole of the power supply, flow through each component without a return path, and finally flow to then the branch ends.
[0034] 2) The components in the tree diagram are divided into different...
