要約(英語): In this paper a modified zero-voltage zero-current transition network (MZVZCTN) is proposed for a charge-pump based dual boost converter. The proposed soft-switching network consists of two diodes, an auxiliary switch and a resonating inductor. To prevent the failure of zero-current transition of the main switches, auxiliary-capacitors are connected across the diodes of the soft-switching network. The high boost ratio is realized with charge-pump capacitor introduced on the load side. The MZVZCTN network is activated two times in a switching cycle in order to ensure zero-voltage turn-ON and zero-current turn-OFF of the main switching devices. Furthermore, the proposed network also ensures zero-current turn-OFF of the main diodes and does not impose any extra voltage stresses on the devices. The converter can operate at a constant frequency of operation with pulse width modulated control. A 460W prototype operating at a frequency of 50kHz is constructed, soft-transitions of the devices and improvement in efficency is validated through experiments.
