Abstract: The topology of the front DC/DC converter for gridconnected PV(photovoltaic) system was confirmed, and the principle and small signal model of the converter was introduced. Based on the model and analysis, the parameters of the main circuit, drive circuit and protection circuit, and control circuit of the Boost DC/DC converter were introduced in detail. The experimental results of the front DC/DC converter for 1 kW PV system show the correctness of the design.
Key words: gridconnected PV system; DC/DC converter; Boost circuit
