Research on the Synchronous Control Strategy of Boost Converter of Photovoltaic Generation System
The output of photovoltaic generation system is of stochastic volatility that influenced by environmental factors such as light intensity, temperature. To track the maximum power point of photovoltaic cells on the boost converter can achieve its maximum output in real time. The voltage gain of boost converter is more efficient, simple and convenient calculation in continuous current mode (CCM). But it requires larger inductance value to maintain the continuous current mode when the output of photovoltaic cells is lower, this will increase the size and cost of components. In this paper, the diode in Boost converter is replaced by field-effect transistor, it can reduce the inductance value,and improve the control performance and conversion efficiency at the same time. MATLAB simulations prove the validity of proposed control method.
