High Efficiency High Power Boost DCDC Converters for Photovoltaic Applications
Języki publikacji
Abstrakty
Współczesne wymogi ochrony środowiska naturalnego przyspieszyły wykorzystanie efektywnych i energooszczędnych technologii w odnawialnych źródłach energii. W artykule omówiono problematykę strat mocy i sprawności podwyższających przekształtników DC/DC o dużej mocy, zasilanych niskim napięciem dla zastosowań w systemach fotowoltaicznych. Biorąc pod uwagę najnowsze rozwiązania, częstotliwość przełączeń takich przekształtników osiąga od 25 kHz dla elementów IGBT aż do 100 kHz dla tranzystorów mocy typu MOSFET, a sprawność osiąga nawet 98%, zależnie od warunków obciążenia.
Recent environmental issues have accelerated the use of more efficient and energy saving technologies in renewable energy source. High power high efficiency boost DC/DC converters for use in photovoltaic, fuel cell and so on will be discussed in this paper from the viewpoint of power losses and efficiency. Considering the state of the art, switching frequency of these converters is in the range from 25 kHz with IGBTs to 100 kHz with power MOSFETs, and the highest efficiency is close to 98 % depending on the load condition.
