Abstract :
It is of advantage to harvest and dispatch power within a minimal number of conversion steps. This paper proposes a single-stage multi-input multi-output converter (MIMOC), which can be used for interfacing diverse energy sources and loads in future smart homes with dc power distribution architectures. The proposed MIMOC offers compact structure, centralized control, galvanic isolation, and wide voltage conversion ratio with precise voltage regulation. The operation principle of the proposed MIMOC is analyzed. A specific switching pattern is proposed, and a multivariable PI based control scheme is presented that enables budgeting the input powers coming from different sources in addition to regulating several output voltages. Both switch and average models are provided to validate the operation of the proposed MIMOC.
