Each of these ultra-compact power supply designs for 800V BEV systems features a planar transformer and showcases the space-saving and reliability benefits of 1700 V SiC-based InnoSwitch3-AQ switcher ICs. okt.to/m40Fju okt.to/CoVe1U okt.to/hLGfAw
Debug the specs "Much of the essence of building a program is in fact the debugging of the specification." ~Fred Brooks, American computer scientist and software engineer Replace the word program with #PowerConverter, and the statement would still be correct.
#CoolingTips Just a little whiff of air goes a long way in cooling your power device! Notice the steep drop in #ThermalResistance of a #Heatsink at low air velocity. Image source: Austin Hughes, "Electric Motors and Drives: Fundamentals, Types and Applications"
The latest data shows that 92.5% of all investments in new electricity generation capacity worldwide went into renewables. [This is for 2024 and comes from IRENA.]
continuing with my PEEC solver in Blender for inductors. Now I have a basic Python/Numba code that can calculate skin and proximity. You can see as the frequency increases the current shifts towards to the outer surface and also gets affected by adjacent turns #b3d #geometrynodes #electronics #Technology #science
