This paper presents the steady-state analysis of series resonant converter (SRC) using the extended describing function (EDF) method. The EDF method is used to express non-linear terms of switching waveforms as linear descriptors to develop a linear model of the converter. The converter under consideration consists of a half-bridge inverter and a full-wave rectifier. The steady-state analysis in the...
This paper proposes a systematic approach to design the output filter of a 10 kW, low-voltage 400 Vll,rms, fouroutput phase, hard-switched AC source based on the Three-Level Neutral Point Clamped Voltage Source Converter topology. Given specifications of the AC source, such as the voltage quality, the control performance or the conducted EMI at the output of the source, are translated into corresponding...
The choice of switching frequency is a very important issue for the development of Parallel Active Power Filter (PAPF), but so far is lack of discussion in a quantitative manner from previous publications. In this paper, an extensive analysis on the switching frequency to the performance of PAPF is carried out, and a specification of the switching frequency values with different compensation results...
