Regulator Topologies For Battery-Powered Systems - AN660

چکیده
Portable computers and digital assistants usually require more than one power supply. These devices may need an AC/DC adapter or battery charger, a high-voltage DC/AC converter for the backlight, and other supplies for lasers, cellular radio transmitters, and auxiliaries. Swapping components in a basic switching-regulator layout alters the circuit topology to create regulators that step up, step down, or invert an input voltage. Substituting a transformer for the inductor produces at least two more regulator circuits or auxiliary output voltages.

Vehicles: Specifications, Topologies and a Practical Example
Battery chargers are essential components for further development of plug-in vehicles including electric or hybrid electric vehicles. The 3.3kW battery charges are widely used in plug-in vehicles in which the power source is the single phase ac grid. The auto industry has stringent requirements on the size, efficiency, temperature and packaging of the onboard chargers that are reviewed in this ...
متن کاملLow Voltage Analog Circuit Design Technqiues - IEEE Circuits and Systems Magazine
The desire for portability of electronic equipment generated a need for low power systems in batteryoperated products like hearing aids, implantable cardiac pacemakers, cellphones, and hand held multimedia terminals. Low power dissipation is attractive, and perhaps even essential in these applications to have reasonable battery life and weight. The ultimate goal in design is close to having bat...
متن کاملPSAR: power-source-aware routing in ZigBee networks
ZigBee is a recent wireless networking technology built on IEEE 802.15.4 standard and designed especially for low-data rate and low-duty cycle applications such as home and building automation and sensor networks. One of the primary goals of ZigBee is low power consumption and therefore long-living networks. Despite this goal, current network formation and routing protocols described in the Zig...
متن کاملLifetime-Aware Battery Allocation for Wireless Sensor Network under Cost Constraints
Battery-powered wireless sensor networks are prone to premature failures because some nodes deplete their batteries more rapidly than others due to workload variations, the many-to-one traffic pattern, and heterogeneous hardware. Most previous sensor network lifetime enhancement techniques focused on balancing the power distribution, assuming the usage of the identical battery. This paper propo...
