  • Planar magnetic based design technologies have been widely applied to power design for better cooling and ease of fabrication. The planar transformer and the planar inductor have a low profile characteristics compare to the conventional transformer which would be more cubical in volume. High frequency operation of magnetic components is a main key to achieve high power density of the power module. However, at a high frequency, the skin effect and the proximity effect have to be considered very significantly in magnetic design and also the parasitics in the converter cannot be ignored. This paper deals with the design and the experiment of planar integrated magnetic component. The optimal design for planar magnetics is summarized.

  • This paper presents the design and implementation of a low-profile power supply developed for AC-PDP application systems. In the proposed power supply, planar magnetics and SMD devices are integrated into advanced power conversion techniques to implement a low-profile power supply applicable to most AC-PDP application systems. Engineering details on the design and fabrication of planar magnetic components are presented. The performance of the prototype power supply is also demonstrated to validate the application potentials of the proposed power supply.

  • 48-V ISG (Integrated Starter Generator) system has attracted attention to improve the fuel efficiency of ICE (Internal Combustion Engine) vehicle. One of the key components that significantly affects the cost and performance of the 48-V ISG system is the motor. In an ISG motor, the core and copper loss make the motor efficiency change because the motor has a broad driving operated range and more diverse driving modes compared with other motors. When designing an ISG motor, the selection of an electrical steel sheet is important, because the electrical steel sheet directly influences the efficiency of the motor. In this paper, the efficiency of the ISG motor, considering core loss and copper loss, is analyzed by testing different types of electrical steel sheets with respect to the driving speed range and mode. Using the results of a finite element method (FEM) analysis, a method to select the electrical steel sheet is proposed. This method considers the cost of the steel sheet and the efficiency according to driving mode frequency during the design process of the motor. A wound rotor synchronous machine (WRSM) was applied to the ISG motor in this study.

  • This paper discusses the development of a 3.5 kW switched reluctance motor (SRM)-based electric air-conditioning (AC) compressor, focusing primarily on the design aspects of the SRM and the integrated controller. In addition to the increased price of rare-earth magnets, SRM's operation capability at high speed and high temperature makes the SRM a viable alternative to the permanent magnet motor for electrically driven automotive air conditioning compressors. A compact and energy efficient scroll compressor is designed and constructed. Two feasible SRM topologies are considered, in terms of efficiency, torque ripple, and acoustic noise. Compact drive electronics are designed and employed to drive the SRM-based compressor. The static and dynamic performance is validated by simulation and experiment.

  • An improved current-fed push-pull PWM converter with integrated magnetics is presented. With this improved topology, the design of magnetic elements such as an inductor and a transformer becomes easier than that using the conventional topology, especially when the converter is suffered from an extremely high input current. Since this gives twice the voltage conversion ratio compared to the conventional one, it is also suited for the high voltage step-up power conversion process. The operation of the proposed converter is thoroughly analyzed. Also, the theoretical analysis and experimental results are taken from the laboratory level prototype.

  • High density power supply technology has been researched over the last few years. In this paper, integrated LLCT(Inductor-Inductor-Capacitor-Transformer) structure is described for use in the half-bridge series resonant converter. The structure is analysed by means of FEMM(Finite Element Method Magnetics) and the experimental results of an U structure for a 300W converter we presented.
