| Abstract |
The series-resonant converter is one of the major classes of electronic power converters that are extensively applied in de-de converters. This technology transfers bulk energy, through a series-resonant circuit in the direct path of the energy transfer. The paper aims to introduce a de-de converter based on a new zero-current-switching (ZCS) series-resonant inverter (SRI) topology. The proposed inverter includes, two switches, and two resonant paths C-L1 and C-L2 (Figure 1). Its main advantages are as follows: output voltage control, reasonable output voltage ripple values, simple structure of the power and control circuits, high frequency operation, soft switching at turn-on/off of the power devices.
The paper presents the basic principles and the theoretical analysis of the proposed de-de converter, the analysis of the output voltage ripple, some considerations on the commutation and turn-on/off switches losses, and the PSpice simulation and experimental converter waveforms. |
