Abstract

Abstract: With the development and utilization of renewable energy, the DC collection of photovoltaics has solved the difficult problem of photovoltaic transmission, and the research of high-voltage and high-power converters has become the key. The boost full-bridge isolated converter (BFBIC) is used as the basic boost module, and the voltage level of the DC transmission line is reached through the independent input of the photovoltaic array and the parallel output of the boost converter. Moreover, after analysing the working principle of BFBIC and introducing the control transfer function of the boost module, this paper combines the principle of maximum power point tracking (MPPT), and adopts the classic double closed-loop control strategy. Finally, the simulation model is built in RTDS. By considering the operation of the system under the conditions of constant irradiation and changing irradiation, the simulation results verifies the feasibility of the system.
