  Power Conversion
It takes incoming AC power from a mains connection through a bridge rectifier converting it to a steady DC supply that is filtered with Bus capacitors.
The DC-to-AC converter section is commonly called the "Power Stage." The most common power stage architect consists of 6 power transistors that provide the ability to connect each of the three motor leads to either the positive or negative of the bus supply.
The power section is dealing with high voltages and high currents that work to develop relatively high loss in the drive.

 Power Management DesignLine | Power conversion platforms help reduce IT equipment power consumption   (Site not responding. Last check: )
Over 50 percent of typical data center power consumption today is used for power delivery, thus operational costs are starting to outstrip the cost of equipment itself.
"Power delivery is obviously a critical factor in the data center and AMD is excited about the ColdWatt solution and the positive impact we expect it will have at the system level in combination with the leading performance-per-watt delivered by the AMD Opteron processor with Direct Connect Architecture."
Thus, ColdWatt's front-end power supplies are able to significantly exceed the 70 percent efficiency level of commodity power supplies, with power headroom to scale with processing density increases and feature additions.

 The Inevitable Direction of the Power Conversion Industry
In the last few years, power supply has evolved from an afterthought to a subsystem that is critical to meeting system-level performance requirements.
Because of severe time constraints, most power supply designs have little time to incorporate revolutionary ideas — particularly since current market solutions work and are accepted by everyone, including end consumers.
The multidisciplinary breadth of power electronics also presents the opportunity for parallel advances in one of the disciplines to rub off on power technology.

 Power / Energy Conversion
We are confronted every day by the notions of Energy and Power: Cars and motors are sold by Horsepower, lightbulbs by Watts, natural gas by Therms, electricity by Kilowatt-Hours, and air conditioners by Tons or BTUs per hour.
Power is simply the rate at which energy is converted (for example, a Watt is one Joule per Second).
Always remember that, in every energy conversion, some of it goes where you want it, and some goes elsewhere (usually heat).

 Green, leafy spinach may soon power more than Popeye's biceps - MIT News Office
For the first time, MIT researchers have incorporated a plant's ability to convert sunlight to energy into a solid-state electronic "spinach sandwich" device that may one day power laptops and cell phones.
The researchers hope to achieve a power conversion efficiency of 20 percent or more (which would provide an extremely efficient power source) by creating multiple layers of PSI or assembling them on rough surfaces or 3-D surfaces, like skyscrapers that concentrate a huge amount of surface area within a relatively small space.
Patrick J. Kiley (S.B. 2003) of MIT also worked on this research, which is funded by the Defense Advanced Research Projects Agency, the Air Force Office of Scientific Research, and the National Science Foundation.
