Research on DC Grid Power Characteristics and DC Active Power Filtering

Abstract:

When nonlinear load is powered by DC grid, harmonic currents and distortion power are produced. At first, the concept of the DC active power filter (DC-APF) is presented in this paper after the analysis of instantaneous power and power factor in the DC network. The DC-APF includes the parallel type, the series type and the series-parallel type, etc. The circuit topologies and the working principles of two kinds of DC-APF are proposed and analyzed: (1) the general type, which can compensate harmonic currents and reactive currents; (2) the correction type, which can track the DC voltage. The comprehensive simulation analysis of the double-bridge half-controlled DC-APF by means of MATLAB/SIMULINK and the experiment of the correction type prove the validity and the feasibility of these topologies and operating principles.
