The large-size planar DC bus bar is widely used in high power converters, whose stray parameters are significantly affected the converter reliability and performance. Taking the example of an actual 315kW/400V inverter, the design, simulation and analysis for its bus bar stray parameters is described in detailed. Being different from the conventional method that considers the bus bar conductor as...
Photovoltaic application of LED lighting has been a hot trend in residential illumination, for it integrates the advantages of both the PV systems and LED lights. However, it has a series of problems, such as high thermal loss, poor reliability, and a short life span. To address these problems, this paper presents a deep research on the whole system from a low-cost, high-efficiency and long-life point...
Integrated gate commutated thyristors (IGCTs) are commonly used for high-voltage three-level pulsewidth-modulation-controlled voltage-source inverters. IGCTs are utilized in series connection when the output voltage is greater than the maximum rated voltage. Special measure must be taken to ensure the safety and reliable operation of the inverters, and to equalize the voltages across the IGCT modules,...
