Abstract
In industry, Boost converter is widely used in PV systems, microgrids and electric vehicles. In the components of Boost converter, the LC filter plays important roles to ensure the high-performance of Boost converter. To guarantee the economic and reliable operations of Boost converter, the efficiency of Boost converter is a significant aspect to be optimized with respect to the LC filter design. However, the optimization of the efficiency of Boost converter will always lead to the deterioration of the power density, so the trade-off relationships between efficiency and power density need to be considered in the design of Boost converter. In this paper, to consider both the efficiency and power density simultaneously in the design of LC filter, a three-stage design methodology is proposed. Following the design methodology, some design examples are given and verified experimentally.
