Inertance Makes Power Electronics Visible
An interactive hydraulic simulator explains switching power conversion through water pressure, flow, inertia, and live electrical waveforms.
Field notes
The simulator maps a switched converter into a hydraulic system, then keeps the water view, electrical schematic, and waveform aligned to the same point in time. Its first public circuit is a buck converter with adjustable duty cycle, inductance, capacitance, and load, plus calculated ripple and min/mean/max waveform values. The page explicitly separates the useful intuition from the analogy’s limits, including nonlinear pipe resistance and the absence of an honest semiconductor model.
