Description
Summary:Passive filter is extensively used in new power systems because of its mature technology and low cost, and two types of high pass (HP) filters, i.e. the second-order HP filter and type-c damped filter, are widely used for harmonic treatment However, the existing researches cannot yet clearly reveal the characteristics of each type of filters, which makes it difficult for the designer to select the optimal filter topology under different circumstances. As a result, this paper provides a deep insight into the topological characteristics of the two types of HP filters with focus on the influence of system voltage on the filter cost, and summarizes the inherent characteristics of the two type of HP filters and their optimal application scenarios. Universal conclusions are reached in the paper, which are applicable to different voltage levels ranging from low voltage to high voltage, and helpful to solve the problem of filter topology selection and guide the design of filter packages.
