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

Interleaved GaN based DC-DC converter requires phase shifted signals. Modern microcontrollers allow to implement such PWM signals and introduce different control methods of current or voltage. #GaN #DC_DCconverter #highswitchingfrequency
