Overview
The power electronics pattern language is the language that allows the composition of a Universal Power Supply – a device that powers any electrical devices such as: induction furnace, welder, laser cutter, plasma cutter, inverter, converter, charger, wind turbine charge controller, electric motor controller, and others. The Power Electronics Construction Set (PECS) is the set of techniques and tools for building such a Universal Power Supply. The pattern involved is:
Details
- Allowance for quick-connect input and output of electrical power of any magnitude, including DC and AC of any frequency
- All functionality occurs via plug-in 'black boxes' of functionality
- All control of current, voltage, frequency, and timing occurs internally via a number of modules with quick-connect inputs and outputs
- Current and voltage magnitude scaling is achieved by plug-in addition of components, such as transistors
- Repair of sensitive components is achievable via plug-in of components
- Mechanical clamp-down secures sensitive components and heat sinks
- Scalable cooling mechanism is achieved via plug-in fans or liquid cooling.

Heatsink design is important when designing these types of power supplies. A mechanical engineer may be better at tackling that portion.
Does it matter which ECAD tools I use? I suspect I should use Eagle since it's the free tool.
Free and open tools are preferable.
Also, by scalable, do you mean putting supplies together in parallel, or swapping out components for higher power versions?
I am thinking more about parallel operation in phase with one another - but another option would be also swapping components or adding components.
The way I see it - have a uniform brain unit - and plug as many power stages to it as needed in parallel, or plug in a single large power stage.
The design should be optimized for lifetime design - you can swap burnt components easily. I am really thinking about universal 'funcional modules' such as sine generator, power stage - basically - if we do a breakdown diagram of functions - these functions may be reused in different applications: welders, induction furnace, plasma cutter, etc.
So the highest level of modularity is best - for a 'power electronics construction set.'
