"The design of magnetics components is the easiest place to jeopardise a #PowerSupply design project." ~Robert Mammano, Father of PWM Controller IC Industry

Learn to design better #magnetics. Wind your own business!

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.

The latest data shows that 92.5% of all investments in new electricity generation capacity worldwide went into renewables.

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

How to calculate the voltage undershoot (ΔVo) of an SMPS during a load step (ΔIo)?

ΔVo = ΔIo/ (2π fc Co)

where
fc = Cross-over frequency of the control loop
Co = Output capacitance

#PWM is beautiful.

[GaN_based_converter @BasedGan63795]

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.
