Please help me in analysis and modeling of a switching power converter where various switches are operating at various switching frequencies simultaneously. Any related literature is highly welcomed.
In the attached paper, modeling of the back-to-back voltage source converter for permanent magnet synchronous generator. The control system is based on model predictive control, which gives variable switching frequency.
If I got the core of your question clear, it's interesting topic to be investigated. Since multilevel converters used relatively recently, the multi carrier different frequency signals applications are researched not thoroughly. I found recently one work with exact the same issue (see the attach). We can face the investigation of multi carrier (the same) frequency more often.
More clearly my current objective is to understand the state space modeling of a switching dc-dc converter where various switches are operating at different switching frequencies. Please help me in finding any related literature.
