A Novel DC to AC Converter Topology based on Magnetic Flux Rate Switching

This paper presents a novel DC to AC converter topology based on the principle of magnetic flux rate switching. The proposed converter has the flexibility to operate either in single or dual output mode of operation, which is decided by the low voltage, high frequency control switches. This paper includes an in-depth modeling of the proposed converter by using bond graph model which is a graphical modeling technique. The magnetic circuit and it's associated non-idealities are represented using gyrator - capacitor model. Dynamic equations of the proposed converter are formulated from the model and is simulated in the MATLAB-SIMULINK platform. A hardware prototype of the proposed isolated converter is built by using a commercially available three legged EE - type core. Efficacy of the gyrator capacitor model is verified by correlating the simulated results with the captured experimental results of the proposed converter.
