	Rectification is the conversion of AC to DC. A universal power supply would require one or two rectifying stages: one at the AC input to provide DC for the voltage converter, and another if the voltage converter is a proper Active PFC converter, which produces PWM shaped output.

	~~Rectifyers~~ can be either passive schottky diode bridges, or active (IC-controlled) MOSFET H-bridges. Passive ones are cheaper, and ultimately more efficient for very high currents, while active ones are superior for low-medium-and-maybe-high currents yet more expensive.

	Off-the-shelf inverters have about a 2 year lifetime, and 5-10 year lifetime for higher quality models. Lifetime design inverters with plug-in replacement components are required for sustainable communities which use battery storage as a component of their electricity infrastructure. One of the few other feasible, non-battery, non-fuel energy storage may be via heat storage coupled to thermoelectric generators, or possibly thermal storage via phase-change salts and heat engines.
