Objectives: Development of adapted plug and play multisource converters based on innovation in power electronics
and control strategies.
Energetic point of view:
· Innovation in power electronics is mainly to enhance the efficiency of the power converter in order to reduce as
much as possible losses in the supply chain.
· Innovative control strategies for management of the power sources and storage systems have to be implemented in
the control part of the converter.
Electrical point of view:
· The converter has to be in accordance with the need in terms of power quality, especially for EMC considerations.
· Innovative control strategies for management of the power quality and security have to be implemented in the
control part of the converter.
Environmental point of view:
· The converter has to be adapted to its environment and its use. By the way, the main part is to work on the
roughness, safety operation and the life time of the product
Description of work : Mains tasks
Approach: This work will be organized in three parallel ways with the aid of three subcontractors:
Task 4.1: (M0 to M 16) Development of “efficient” power converters. Today power converters for energy management
are mainly derived from UPS, motor drives. This technology offers an oversized current or voltage quality against losses
considering the efficiency of the power conversion. CIRTEM has innovative plans to really enhance power efficiency with a
technology that should respect power quality requirements. In this task, CIRTEM develops hardware prototypes (made of
power electronics) that will cover the needs in power conversion for the project. Helped by the fact that reducing losses in
power conversion enhances life time (low stress on components), CIRTEM will also focuses during development of the
prototype on the roughness of the converter face to environmental aspects as humidity, lightning, transport, heat, etc to
maximise operation of the system and minimise faults.
Task 4.2 : (M0to M 24) Implementation of the “plug and play” strategy. At the same time, results of workpackages 2 and
3 in terms of control strategy must be implemented on a hardware and software structure, compatible with power part of the
converter. Strategies deal with management of power sources and storage elements on one way, and power quality, faults
detection and security on the other way. By working with ISSIA and University of Nottingham on their results and the way to
implement it in the power converter control part, CIRTEM develops a control system for its converter that enables plug and
play strategy and communication between converters if necessary.
Task 4.3 : (M0 to M 24) Interface with the toolbox. Configuration of control strategy will be done by using the toolbox, the
software part of the project that makes the link between the need (of the client) and the adequate control strategy of the power
system (the product). Power converters are the levers to manage the system and their control part must be interfaced and
configured by the toolbox. In relation with the “toolbox software” developed by SASSO, CIRTEM develops an interface able
to configure converters control strategy in accordance with decisions make by the user through the toolbox.

Deliverables
· D4.1 Analysis on different types of conversion topologies, filtering technologies and commands to make the best
compromise between power efficiency and quality.
· D4.2 Design of different power converter prototypes, taking into account results of the analysis and future hardware
needs for the implementation of the control strategies.
· D4.3 Fabrication and tuning of the power converter prototypes.
· D4.4 Implementation of the control strategies (software) for the plug and play ability.
· D4.5 Installation on site tuning and testing of the different strategies. Validation.
· D4.6 Interface with the toolbox. Configuration of the system controlled by the toolbox.

Milestones and expected result

elements.
· M 4.17 Meeting with University of Nottingham to discuss on the control strategy for the power quality.
· M 4.20 Installation on site of the prototypes with SASSO.
· M 4.24 Meeting with SASSO to discuss on the development method for the interface between the converter
controls and the toolbox.
· R 4.1 Development of plug and play multisource converters.
· R 1.2 Installation and go back on a real scale system
