Abstract-This paper proposes a new isolated, three-port, bidirectional, DC-DC converter for simultaneous power management of multiple energy sources. The proposed converter has the advantage of using the least number of switches and soft switching for the main switch, which is realized by using a LCL-resonant circuit. The converter is capable of interfacing sources of different voltage-current characteristics with a load and/or a DC microgrid. The proposed converter is constructed for simultaneous power management of a photovoltaic (PV) panel, a rechargeable battery, and a load. Simulation and experimental results show that the proposed converter is capable of maximum power point tracking control for the PV panel when there is solar radiation and controlling the charge and discharge of the battery when there is surplus energy and power deficiency with respect to the load, respectively.

“…In recent years, more and more mechatronic applications (electric windows, electric clutch actuator, intelligent power closer systems, robotized gearbox…) including dc-dc converters are introduced in the automotive domain [1] [2] [3] [4].The operation of these converters depends on many physical domains strongly linked. Depending of the designer specifications and the real environment of the operation for these converters, several constraints (electrical, thermal, mechanical, volume, control and cost) must be taken into account in their pre-sizing.…”

This paper presents an optimization approach to pre-size dc-dc converters by integration of the control constraint. This approach is carried out in two main steps. The first step consists on determining the most adapted architecture to answer the specifications and the appropriate technologies of the passive and the active components of the selected architecture representing the minimal of the major constraint (like volume or cost). In addition, the designer can have an evolution of this major constraint by technology considered for each component (active and passive) and used in the chosen architecture. The models used in these step are developed from manufacturer datasheets. The second step consists on optimizing the selected architecture by considering the appropriate technologies resulting from the first step under multi-physic constraints: thermal, losses (or efficiency), volume, electromagnetic compatibility and control constraints …. The proposed approach allows reducing significantly the computing time which is suitable in a pre-sizing phase where several parameters must be optimized and multi-physic constraints must be respected.

“…If a supercapacitor is chosen as the storage, the energy storage capacity of the supercapacitor cannot be fully utilised because the energy is proportional to the square of the terminal voltage. An example of this converter can be found in [18] for electrical vehicle applications. Figure 9 illustrates a further possibility to use the boosthalf-bridge in order to realise a current-fed port for a storage device or fuel cell.…”

Multiport DC-DC converters are of potential interest in applications such as generation systems utilising multiple sustainable energy sources. A family of multiport bidirectional DC-DC converters derived from a general topology is presented. The topology shows a combination of DC-link and magnetic coupling. This structure makes use of both methods to interconnect multiple sources without the penalty of extra conversion or additional switches. The resulting converters have the advantage of being simple in topology and have a minimum number of power devices. The proposed general topology and basic cells show several possibilities to construct a multiport converter for particular applications and provide a solution to integrate diverse sources owing to their flexibility in structure. The system features a minimal number of conversion steps, low cost and compact packaging. In addition, the control and power management of the converter by a single digital processor is possible. The centralised control eliminates complicated communication structures that would be necessary in the conventional structure based on separate conversion stages. A control strategy based on classical control theory is proposed, showing a multiple PIDloop structure. The general topology and a set of three-port embodiments are detailed.
