The increasing demand for higher power density and lower cost in high voltage power supplies has driven semiconductor manufacturers to expand IGBT performance for high switching frequency beyond 100 kHz. An ultra thin punch-through IGBT with a blocking voltage of 650V has been developed and optimized targeting DC-DC conversion up to 200 kHz. Its high Tjmax of 175°C further enhances the converter compactness...
Advanced transportation technologies, such as hybrid-electric, battery-electric, and hybrid-fuel-cell vehicles, rely on high-power dc/dc converters to interconnect and manage their power sources. Boost converters are particularly useful in stepping up the voltage from a battery or fuel cell to match the traction motor operating voltage range. High-frequency high-efficiency operation is crucial so...
Summary form only given. This paper extends previous approaches that use electromagnetic transient simulation to estimate the switching and conduction losses of insulated-gate bipolar transistor-based voltage-sourced converters embedded in large electrical networks. In contrast to earlier approaches, which merely estimate and report the device loss, the proposed new model also reflects this loss back...
