Common power problems - Technologies (Offline / standby, Lineinteractive,
Online / double-conversion) - Other designs (Hybrid topology /
double conversion on demand, Ferro-resonant, DC power, Rotary) -
Applications ( N+1, Multiple redundancy, Outdoor use, Internal systems) -
Machine standards ( Measuring efficiency, Warranty) - Difficulties faced with
generator use - Communication - Batteries ( Common battery characteristics
and load testing, Testing of strings of batteries/cells, Series-parallel battery
interactions, Series new/old battery interactions).
