... In theory, these diodes have a negative resistance slope in one portion of their characteristic curve, making them capable of amplification and oscillation. See Figure 1. In actual practice, however, we have aproblem if we try t o look at this slope. Any simple circuit that we can devise to graduall ...

Installation Manual
... The AC source going into the inverter must have a neutral conductor bonded to ground (i.e. 3-prong wall cable). When the inverter is passing AC power through, it relies on the input being grounded to ensure the power delivered to a sub-panel is bonded. See “AC Output Neutral Bonding” on page 12 for ...

Buck converter
A buck converter is a voltage step down and current step up converter.The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
