Description
A dc grid becomes an obvious trend in the residential power system. Recent works show that even a high-voltage dc-current distribution system is more effective than a high-voltage ac system. Due to the latest research efforts in power electronics, the high-voltage dc-current system may replace an ac system in the coming decades. The dc low-voltage distributed system may become a reality even sooner.
At the same time, it is evident that transient from ac to dc grid cannot be done immediately. In the nearest decade, we will observe a merge of dc and ac systems. As a result, the power electronics facilities that have the ability to merge dc and ac grids are required.
The main goal of this work is to develop the hybrid power electronic converter suitable for dc and ac residential grid application with minimum redundancy.
There are several tasks that will be solved during PhD study:
- To propose the optimal power electronics topology which can integrate high-voltage batteries (300 V-700 V) along with solar energy into dc or ac grid
- To investigate the way of power density and cost optimization of the proposed solutions
- Implementation of the conventional control algorithms for grid-connection realization along with wide input voltage regulation, maintaining MPPT and SoC control technique
- Research and development of the novel control algorithms for grid-type detecting and smooth connection/disconnection
- Development of the industrial prototype of new 3.3 kVA DC-DC/AC hybrid converter
The applicants should fulfill the following requirements:
- Practical experience in the design of electronic systems
- Experience with programming of microcontrollers for power electronics application
- Experience with electronic circuits modeling in (Matlab, PSIM or PSCAD)
- Experience with PCB design preferably using Altium Designer
- Experience with closed-loop control systems featuring analog and digital sensors
