Buck converter — CCM
A simple step-down converter with continuous inductor current.
Converter examples you can edit
Open a working circuit in the app, change one value, and run it again. A “Validated” label only covers the specific checks listed for that example.
Buck — CCM/DCM load boundary
A load sweep that shows when the inductor current stops flowing continuously.
Buck — startup vs periodic steady state
The same buck converter shown during startup and at repeating steady state.
Boost converter — CCM
A 2.5 V to 3.3 V step-up converter with continuous inductor current.
Boost — duty and load sweeps
Separate sweeps for switch duty and output load.
Flyback converter — CCM
A 48 V isolated flyback converter with continuous inductor current.
Flyback — turns ratio and load
A flyback converter for testing transformer ratio and output load separately.
PI buck — 5 V regulation
A 12 V to 5 V buck with a sampled PI voltage controller.
PI buck — line and load steps
A controlled buck responding to input-voltage and load changes.
Hysteretic buck
A comparator-controlled buck with a variable switching frequency.
Duty-commanded buck — control-to-output
A buck whose duty is a command, so its frequency response to that command can be measured.
Peak current-mode buck
A buck that turns its switch off when inductor current reaches the set value.
Peak current-mode buck — command and load
A peak-current buck for testing current command, load, and slope compensation.
Diode reverse-recovery pulse
A detailed diode model switching from forward current to reverse voltage.
IGBT clamped inductive switching
One hard-switching event with an inductive load and voltage clamp.
Thyristor latching load switch
An SCR switched on into a resistive load and kept above its holding current.
Saturable inductor knee
A magnetic-core inductor driven into saturation.
DC motor start-up
A brushed DC motor showing startup current and rising back-EMF.
