Development of a controller for fuel cell and supercapacitor application
Rautenbach, H.J.; Gouws, R.; Bessarabov, D.; Kruger, A.; Human, G. (CATSA (Catalysis Society of South Africa), 2014)The growing demand for energy in the world causes a lot of pressure to the environment and the resources used to supply the energy. To ensure a continuous, more reliable and environmentally friendly energy supply system ... -
Improving energy consumption of an induction motor by design of a power factor correction system and estimation of it's saving on a large scale
Zabihi, N.; Gouws, R. (IEEE, 2014)Power factor correction (PFC) is common in commercial and industrial applications. A need to extend its application increased with the dwindling natural resources used for power generation and also exceeding energy demand, ... -
In-line water heating system for industrial application
Dobzhanskyi, O.; Gouws, R.; Zabihi, N. (2015)Due to the increase of electricity prices in South Africa and the World, there exists the need for energy efficient water heating systems. The authors of this paper conducted a literature study on existing water heating ... -
Integration of battery and super-capacitor banks into a single-power system for a hybrid electric vehicle
Bisschoff, W.A.; Dobzhanskyi, O.; Gouws, R. (IEEE, 2016)This paper presents a study on a hybrid electric vehicle for mines and other industrial sectors. The power supply system of the vehicle is designed by combining two sources of power: a battery and super-capacitor banks. ... -
Intelligent controller for improved efficiency of micro wind turbine generators
Botha, S.; Gouws, R. (IEEE, 2016)Due to an ever increasing demand for electricity Eskom is struggling to cope, which inevitably leads to load shedding. Although this is a minor inconvenience for residential users, the effects can be detrimental for ... -
Intelligente beheer van 'n effektiewe hernubare-energie tenk vir melkboerdery
Pelser, W.A.; Gouws, R. (2014)To reduce strain on Eskom and decrease the cost for producing dairy products, an energy-efficient bulk storage tank using solar power was designed. The system uses thermoelectric cooling modules as a supporting cooling ... -
Measurement and verification of the Eskom irrigation pumping standard product programme
Storm, M.E.; Gouws, R.; Grobler, L.J. (2013)Eskom Integrated Demand Management (IDM) initiated a funding mechanism termed the Standard Product Programme (SPP) to cater for smaller Energy Efficient (EE) projects. The impacts of these projects also need to be assessed ... -
