A novel series input parallel output soft-switching high step-down converter (SIPOSS-HSD) converter is proposed in this paper. The converter consists of two asymmetrical half-bridge high step-down (AHB-HSD) dc-dc converter cells in series input and parallel output connection to share the input voltage and output current. All switches of the proposed SIPOSS-HSD converter can be turned on under zero-voltage...
An interleaved high step-up dc-dc converter is proposed for high voltage gain and high efficiency applications. The configuration is composed of modified two-phase interleaved boost converter with parallel-input series-output connection and a voltage multiplier module stacking on the output side. In the proposed converter, the parallel-input connection is used to share the input current and to reduce...
A new type of piezoelectric transformer which is based on the stress distribution of the piezoelectric transformer to change the output voltage is presented. In this paper, we verified the feasibility of the principle of the new piezoelectric transformer from the simulation and experiment. The experiment results show a good consistent with the theoretical analysis. The designed piezoelectric transformer...
