An Isolated Multiport DC-DC Converter for Different Renewable Energy Sources

K.Pradeepkumar, J.Sudesh Johny

This paper presents a new isolated multiport dc–dc converter for concurrent power management of several renewable energy sources which can be of similar types. The proposed dc–dc converter uses only one controllable switch in each port to which a source is connected. It has simple configuration and minimum number of power switches. The proposed converter is applied for simultaneous maximum power point tracking (MPPT) control of a wind/solar hybrid generation system consisting of one Wind Turbine Generator (WTG) and two different Photovoltaic (PV) panels. The experimental results are provided to validate the incisiveness of using the proposed converter to achieve MPPT simultaneously for the WTG and both PV panels.
