ABSTRACT:
TECHNICAL FIELD
This invention relates to power supply apparatuses and methods of supplying electrical energy.
BACKGROUND OF THE INVENTION
The sophistication and uses of electrical devices have increased dramatically in recent years. Consumer items having electrical components are ubiquitous in communications, computing, entertainment, etc. The size of mobile telephones, notebook computers, music players, and other devices has continued to decrease while the capabilities and quality of the devices continues to increase as modern electronic components used in such devices are developed and improved upon.
Numerous people rely upon or have grown accustomed to usage of electrical consumer devices for business, education, or for other needs. Electronic consumer devices are increasingly portable to accommodate these needs during travels from home or the workplace. The sophistication and capabilities of power supplies for such devices have also improved to meet the requirements of the electronic consumer devices. For example, cost, size, and capacity are some product characteristics which have been improved for the portable power supplies for electronic applications. There is a desire to enhance these and other design parameters of power supplies, including portable power supplies, to accommodate increasing power requirements of modern electronic consumer devices.
