Within the framework of Flexible Electrical Network (FEN) project, different converters with their control strategies are investigated to collect renewable sources, connect loads and finally compose a multi-terminal dc grid at the distribution level. In PGS lab, a downscaled dc-dc converter for PV power collection has been designed and initially tested. Three-phase dual active bridge topology is employed due to its inherent soft switching and galvanic isolation. Besides standard voltage and current control, Maximum Power Point Tracking (MPPT) algorithm has been implemented for the converter. Based on the existing work, this thesis works on further improvement of the control algorithm and protection system to allow more robust operation under various circumstances. With that the complete control system needs to be implemented on a new FPGA based control platform, which will be in the future in communication with a central DSP controller for the system-level control.
a.Improve existing control system e.g. fine tuning of control parameters, implement additional functions. b.Enhance existing protection system: hardware and software c.Control implementation on a FPGA based control platform
- Good knowledge of power electronics, including circuits, control, and devices. - Experience of hardware construction and experiment - Skill of PCB design is preferred.
