This paper proposes a remarkably efficient modeling method of stray magnetic couplings in an Electromagnetic Compatibility (EMC) filter focusing on a dominant magnetic field in a power electronic device. The proposed modeling method is applied to a filter performance simulation of an EMC filter for a Silicon Carbide (SiC) solar inverter and its effectiveness is verified by comparing a measurement...
A novel bridgeless interleaved boost PFC rectifier is proposed for improving power efficiency and system performance in this paper. By combining the conventional bridgeless topology and the interleaved technology, this rectifier is comprised of two interleaved boost branches without the front-end diode bridge. Each branch operates in every half-line cycle, together with the current following through...
Experiments have critical roles in engineering education. However, it is not easy to conduct experiments because of their high costs of equipment and unavailability. Remote experiment systems have coped with this issue. Using remote experiment systems, users can conduct experiments regardless of their locations or times. Remote experiment systems have been developed worldwide, but most of the systems...
Several accelerated test methods exist in order to study the failures mechanisms of the high power IGBT modules like temperature cycling test or power cycles based on DC current pulses. The main drawback is that the test conditions do not represent the real performance and stress conditions of the device in real application. The hypothesis is that ageing of power modules closer to real environment...
In this paper, a novel asymmetrical fuzzy-logic-control (FLC) based maximum power point tracking (MPPT) algorithm for photovoltaic (PV) generation system (PGS) is proposed. The proposed method uses the power variation and voltage variation as the inputs, which significantly simplified the computation. Comparing with the conventional perturb and observe (P&O) method, the proposed asymmetrical FLC-based...
The efficient reduction of EMI noise generated by power converters has been an indispensable technology. In order to meet the requirements of CISPR22, EMI filters have to be equipped with power converters. It is widely known that an EMI filter can be designed more optimally if the designer could know its inherent EMI noise in advance. This paper presents an accurate simulation method for the conducted...
The demand for noise reduction inside a vehicle has been recently increasing in the pursuit of improved ride comfort. In consideration of requirement of quietness improvement and reduction of weight, an active noise control (ANC) system has been attracting much attention. This method is effective for noise with low frequency. In this study, we propose an ANC system by using the vibration of giant...
This paper presents a detail analysis on the design and integration of interphase inductor for interleaved three phase voltage-source-inverters (VSI). The benefits of interleaving on EMI filter weight reduction are presented. Interleaving can cancel certain order of harmonics in the total output current and reduce the size and weight of the EMI filter to meet certain EMI standard. However, it also...
