Workshop on Application of Power Electronics in Recent Industrial Development
Innovations for a turbocharged future
Can power electronics be used to beat the fossil-fuel industry? What is the future of power electronics? To answer these questions, the Department of Electronics and Communications Engineering, Brainware University, invited Dr Jerzy Szymański (Professor, Kazimierz Pulaski University of Technology and Humanities) and Ms. Marta Zurek-Mortka (PhD research scholar, Kazimierz Pulaski University of Technology and Humanities) for a workshop on Application of Power Electronics in Recent Industrial Development on 10 November, 2020.
Dr Szymański initiated the discussion by stating the importance of efficient power electronics in industrial development. “We have seen that the demand for energy grows with the improvement in quality of life. Unprecedented growth is not sustainable for us or the environment hence power optimization is the need of the hour,” he said.
Power Electronics use semiconductors in the production of electrical energy and as industries are a major consumer of electricity, ongoing research efforts have been directed towards creating better devices for power generation. The two main trends in the application of power electronics mentioned by Dr Szymański was the turn towards green energy and decentralization of energy production.
Microprocessor Control Units (MCUs) are used to aid decentralization while Power Electronic Convertors (PECs) are used to control energy flow to ensure optimized generation of electricity.
To give students an idea about real-life implementations of power electronics, Dr Szymański discussed the designs of various micro-grids while talking about the features installed in the grid to enhance their efficiency. Micro-grids are mini energy generators that are often used in industries for supplying additional power. Energy wasted in the form of heat is being minimized through using materials which generate less heat. Additionally, the power grids are being installed with special devices to store the heat energy for later use.
Ms. Zurek-Morta demonstrated the use of hybrid power supply networks and the use of Drive Frequency Converter for EV battery charging. (a little more detail about her presentation will balance this report). Hybrid power supply networks make use of both renewable and non-renewable energy sources to generate power with significant reduction in the overall carbon footprint. “The energy generated from renewable sources is too volatile to be considered as the sole source for industries. A balance of both steady energy supply and renewable sources is profitable both for the environment and for the industries. If we have to act now to save the environment hybrid power supplies are our best options,” said Ms. Zurek-Morta.
