Requirements on Power Electronics for converting Kitchen Appliances from AC to DC 1#

P. van Duijsen, J. Woudstra and D. Zuidervliet, "Requirements on Power Electronics for converting Kitchen Appliances from AC to DC," 2019 International Conference on the Domestic Use of Energy (DUE), Wellington, South Africa, 2019, pp. 190-197. Abstract: The main power source for kitchen appliances for cooking and heating in Europe is natural gas. Since fossil fuels are limited, an energy transition is taking place from fossil fuel supply towards renewable energy such as solar and wind power. Kitchen appliances for cooking and heating have to be converted towards the use of electrical energy. Although many kitchen appliances are available for electrical energy supply, a transition to a DC grid would have benefits regarding control, earth leakage protection and peak power usage. Congestion management is solved via droop control. The bandwidth of droop control in DC grids is significantly higher compared to droop control in AC grids. Droop control enables load sharing during peak power demand. Earth leakage protection in an isolated grid enables early detection of earth faults, before they become critical. Furthermore short circuit protection in a DC grid is implemented via a predictive rate of change of current di/dt measurement, isolating a fault before the short circuit current can grow. The inrush current that exist when directly connecting the AC appliance to a DC grid, can be avoided by using a programmed current limiter which controls the level of the input current. Secondly this current limiter can be used to control the power level in appliances where current control is enough to control the application, such as the resistive heater in an oven.Examples are given on the appliance of a inductive cooking and controlling the heater in an oven.

Electronic Learning Experience Setup : Power Electronics and Electrical Drive Education #2

P. J. van Duijsen, D. C. Zuidervliet and J. B. Woudstra, "Electronic Learning Experience Setup : Power Electronics and Electrical Drive Education," 2020 43rd International Convention on Information, Communication and Electronic Technology (MIPRO), Opatija, Croatia, 2020, pp. 1549-1554, doi: 10.23919/MIPRO48935.2020.9245230.Abstract: A method to teach and instruct the workings of power electronics and electrical drives is presented. The combination and interaction between oral lectures and practical laboratory assignments is presented, as well as the required tools. The structure of the course should consist of individual sections of increasing level regarding subject and details. For each subject the required knowledge level can be examined and a laboratory test has to be passed. Design tools and simulation/animation tools are used throughout the course. The laboratory assignments should follow the theory and simulation/animation is used to show the similarity and differences between theory and practice. A typical power electronics course is given as example and laboratory assignments using a dedicated educational trainer are given.
