A high step-up current fed multi-resonant converter (CFMRC) has been proposed recently for renewable energy harvesting where the sustainable power sources such as PV panels and fuel cells are characterized by low-voltage, high-current output. An output voltage doubler is applied to the previously proposed CFMRC for the purpose of reducing the turns-ratio of the transformer. Compared to the CFMRC with...
It is found out that using reverse coupled inductors could effectively improve power density and dynamic performance of multiphase interleaved point of load converters. Thus, it is of great significance to conduct a research about design and fabrication of ultrathin coupled inductors for system 3-D integration. The aim of this paper is to explore the structures, modeling, and fabrication of ultrathin...
This paper focuses on designing of multi-turn spiral inductors with multilayer parallel-connected conductors for high frequency DC/DC converters based on low temperature co-fired ceramic (LTCC) technology. Effects of conductors' arrangements on performance of LTCC inductors are analyzed. Based on observation and analysis, a model to approximate inductance of LTCC inductors is derived. Simulation results...
Using coupled inductors in multi-phase point of load converters is an effective way to improve system steady state and dynamic performance. Thus, package of coupled inductors for system three-dimensional integration is attracting great interest of research. This paper explores design, fabrication and analysis of planar coupled inductors based on low temperature co-fired ceramic technology. Four structures...
A two-stage topology which is very suitable for 24 V input, low voltage and high current output DC/DC converter is proposed. The first stage is two-phase interleaved Boost for regulating voltage, and the second stage is a fixed 50% duty cycle full-bridge (FB) for isolation and power transmission. To show its advantages in loss reduction, two topologies are also introduced for loss comparison. One...
