=Introduction=
With the principle of [[Part Count Reduction]] within OSE's [[Module Based Design]] approach - we are interested in using this principle to facilitate the design of electronic circuits, and in particular, power electronic circuits.

With low cost microcontrollers (700 Mhz Pi Zero is $5) and transistors (IGBTs are $1/kW of power handling) - we can design low cost power electronics. Let's look at how this can be done for simple learning circuits which can serve as a basis of robust industrial applications. These examples show the limits of power for various devices.

=Inverter=
*10kW direct solar power inverter case using Arduino and IGBTs for $25. Inverter at 120V for regular loads such as power tools.
*Start with 1kW of PV for test, then move to 10kW.
*10kW case is scalable to 100kW
*Slide 12 of [[Open_Source_PV_System#Initial]] shows max power point - current at about 9A and voltage at 31V - for PV panels.
