Journal of solar energy 980409 Acta Energiae Solaris Sinica Journal of solar energy In 1998 nineteenth volume fourth No.4 Vol.19 1998 technical periodicals Comparison of CVT and MPPT control in photovoltaic water pumping system Yu Shijie He Huiruo Cao Renxian (HeFei University of Technology Energy Research Institute, Hefei 230009) Abstract: maximum power point tracker of photovoltaic arrays can make the photovoltaic pump system, the maximum power output in real time. For convenience and reduce the system cost, products of the photovoltaic pump system of most countries in the world are still using constant voltage tracker (CVT), to replace the real maximum power point tracker (MPPT). By computer simulation in this paper further expounds the difference between CVT and MPPT and prove that MPPT is superior to CVT in a large extent, especially for the occasion of winter and summer and a wide range of temperature. Keywords: CVT, MPPT, photovoltaic pump, simulation, comparison of 0 Introduction photovoltaic pump system in recent years, the rapid growth of the number in the world, especially in Africa, South America, Australia and other Asian countries, the growth rate is quite large, in recent 5 years in India photovoltaic pump system newly installed about 4000 sets, even the energy supply is not too tight in Thailand, since 1992 in the country to install photovoltaic pump system of nearly 1000, such as Malaysia, Indonesia, Bangladesh, Burma and many other countries also have a certain growth rate. The reasons for its rapid growth, but is growing rapidly and people of solar batteries, power electronics and microelectronics technology of environmental awareness in recent years, many examples are further proved t
