ABSTRACT
Entering the 21st century human beings are facing to realize the sustainable development of economy and society and energy problem becomes more and more serious on the one hand
conventional energy is serious short on the other hand the development of oil and other conventional energy brings a series of problems such as the environmental pollution the greenhouse effect and so on Only by relying on the progress of science and technology and the large-scale exploitation and utilization of renewable energy and new energy can human solve the problem of energy and realize the sustainable development And solar and wind power are considered the most representative of new and renewable energy The power technology of solar energy and wind attrack worlds attention Because of wind power and solar power system under external conditions and only by independent wind or solar power systems often hard to ensure the continuity and consistency of power system therefore using hybrid power system of complementary scenery to complement each other realize the continuous stable power supply Wind-light complementary with its unique advantages become one of
new energy research hotspots Aiming at wind-light complementary this article design a small device including solar cells in dc motor the simulation and interlacing of fan parallel Buck - hee and main circuit batteries to Buck staggered shunt circuit and interlacing parallel hee - Cuk chopper
were studied and the simulation the simulated fan unit commissioning Control system adopt Freescale company 56F8013 DSP control chart each part The key question for software and hardware to the corresponding solutions KeywordWind and PV hybrid Buck–Boost Circuit DSP
