Fully Optimized Discrete Coupled Inductor DC/DC Converter as The TriMagiC converter
Took deep analysis of coupled inductor system in terms of delta flux density (Bm) to each part (Lk and Lm) separetly. and adopted optimal magnetic material to each part (LiqualloyTM to Lk, Ferrite to Lm) and designed Transformer based on Bm setting. Then could obtain approximately 30% less magnetics size and keep high level converting efficiency.
Ultra Compact 2kW 12V-48V Converter Using a 4-Phase Coupled Inductor
This paper presents the design and experimental validation of a 4-phase interleaved mode 2kW 12V-48Vbidirectional bordnet converter using a 4-phase coupled inductor consisting of low-µ nano-crystalline metaltape. In a first step the design of this inductor and an analytic volume comparison to standard 4-phaseinterleaved mode converters is presented. The design will be based on rho/phi-pareto analysis optimizingthe design process. Finally the paper concludes in the experimental validation of the converter.
Thermal Analysis of a Directly Liquid Cooled Silicon Carbide Resonant Inverter for High Voltage Generation
One approach to reduce volume and weight of high voltage generators used in industrial ormedical applications is the higher integration of the power inverter into the high voltage tank. Therefore, this paper presents investigations concerning the thermal behaviour of a directly liquid cooled silicon carbide resonant inverter for high voltage generation. The designed full-bridge resonant converter based on silicon carbide semiconductors operates at frequencies above 500 kHz and a maximum output power of 80 kW.
Highly Integrated Two-Phase SiC Boost Converter with 3D Printed Fluid Coolers and 3D Printed Inductor Bobbins
Nominated for the Best Paper Award
Nominated for the Young Engineer Award
With the use of Selective Laser Melting (SLM) new 3D printed cooling structures for power converters can be realized. In this paper, a highly integrated two-phase interleaved bidirectional boost converter using discrete SiC-MOSFETs and 3D printed fluid coolers as well as 3D printed inductor bobbins is presented. The converter is operated at a high switching frequency of 400 kHz and features a high power density of 32.6 kW/dm3 while delivering 15 kW of output power.
High Step-Up High-Frequency Zero Voltage Switched GaN-Based Single-Stage Isolated DC-DC Converter for PV Integration and Future DC Grids
In this work, a high step-up single-stage DC-DC micro-converter for photovoltaic (PV) applications is demonstrated. To reduce the size of passive components and the overall system, the circuit was designed to work at a high switching frequency of 300 kHz, using GaN power HEMTs. For the high step-up ratio required in this application, we designed a high-frequency high step-up planar transformer, which enabled a high boost of voltage, in just a single-stage DC-DC converter, reaching an efficiency of 93%.
