The power supplies have no minimum load requirement to bring the units into regulation. All the outputs have overvoltage and short circuit protection plus overcurrent protection as well. Both have individual LED indicators which display a visual status of each regulated output.

Power is input through a standard 2-pin plug and connector system for easy connection and removal. The output voltage is wired directly to the PC/104 connector. On the PCM-DC-AT512 there are also two, four-pin connectors at the edge of the board to provide +5V and +12V to disk drives and other accessories. Both the PCM-DC-AT500 and PCM-DC-AT512 are PC/104 and RoHS-compliant. They measure 3.6” x 3.8” (90mm x 96mm).

Vicor’s IBC Power Simulation tool provides advanced simulation capabilities that enable designers to define and optimize electrical and thermal operating parameters and view the resulting data graphically on screen. The combination of electrical and thermal simulation capabilities allows designers to account for system interdependencies that affect IBC power capability based upon essential variables including input voltage range, load conditions, ambient temperature and airflow. Variables defining external input and output filter elements can be adjusted to minimize input and output ripple and optimize dynamic performance while minimizing the total footprint allocated to IBCs within dense system boards.

The online tool reduces time-consuming manual evaluation/bench processes and streamlines design and development cycles. The ability to track changes across simulations with different parametric settings provides comparative insight speeding up design optimization. It is available for use today online via the PowerBench online design center in combination with Vicor’s new online DC-DC Solution Selector tool. Both tools will be expanded to include Vicor’s full portfolio of high-performance power conversion and management products.

The self-contained energy measurement system features an embedded metrology engine and includes a full range of embedded energy diagnostics, including power factor, harmonic distortion, voltage sag, and dip. The device also provides better than 0.5% system accuracy across a wide 2000:1 dynamic range. This enables the use of the lowest value shunt for the current sensor, thus reducing heat and parasitic power loss. The device’s integrated flash provides application flexibility, on-chip calibration, and field upgrade capability. Furthermore, it is available with preloaded firmware that supports both Delta and Wye 3-phase applications, which reduces both development costs and time to market.

These single output power supplies operate with a wide universal input range of from 90 to 265VAC with PFC and are available with DC outputs of 12V, 28V (adjustable to 24V) or 48VDC. Due to its wide output adjustment range of +/- 20%, the output voltage can be set to match a variety of customer-specific applications. The outputs of these units can be con-nected in series or parallel for higher power applications.

The CPFE1000F series was designed for harsh indoor or outdoor environments and are ideal for such applications as LED signage, RF broadcast, COTS-military, noise-sensitive Audio/Video equipment, food processing and other industrial/commercial applications. The power supply’s baseplate is designed to easily attach to metal enclosures or other heat-sinking surfaces, thus eliminating the need for fans or forced-air-cooling. To guard against moisture, dust and other containments, the internal PCB assembly has a protective coating.

A distinguishing feature of the CPFE1000F series is its internal I2C bus interface which can send operational parameters of the power supply to remote locations. These parameters include: output voltage, output current, baseplate temperature, serial number, model number and date-code. In addition, the I2C interface provides a means to turn the power supply On or Off from a remote site and receive DC Good and over-temperature signals. In addition to the I2C bus, traditional signals/controls are provided including an Output Good signal, Remote On/Off control, Remote-Sense lines, Active Current-Share, and an Auxiliary-Output of 12V/20mA.

All models in the CPFE1000F series include TDK-Lambda’s two-year warranty and meet EN55022/EN55011 Class B and MIL-STD 461/462D CE102 EMC specifications, thereby simplifying system designs.

The Delphi Wireless Device Charging System transmits power over distance to deliver a charge to electronic devices in the vehicle cabin without multiple charging cords.

Delphi Automotive will display its Wireless Device Charging System at the Consumer Electronics Show next week. Currently under development, the wireless charging system transmits power over distance to deliver a charge without precise positioning of the electronic device receiving the charge. It would eliminate the clutter, inconvenience and distractions associated with multiple charging cords in the vehicle cabin and replace them with a safe, convenient and efficient automatic charging system.

“From navigation systems to cell phones to personal computing devices, we are tied to our favorite electronics, but we won’t always have to be tied to charging cords for them to work,” said Christopher Reider, global director of engineering, Delphi Connection Systems. “Instead, our system will use magnetic fields from hidden power source resonators placed in the vehicle interior to automatically power these devices through high-efficiency, hands-free charging.”

Revolutionary Design

Delphi is testing the system on research vehicles and intends to be production-ready by model year 2014. The Delphi Wireless Device Charging System makes use of the same magnetic resonance technology as the Delphi Wireless Electric Vehicle Charging System. Magnetic resonance technology is superior to traditional inductive charging because it can transmit power over greater distances, does not require precise device positioning in order to deliver a charge and will be able to charge multiple devices at the same time. The consumer devices simply need to be in proximity to the power source, not directly touching it. Traditional inductive charging systems are limited to charging only one device per charging coil and the device must be resting on top of the pad to receive a charge.

Multiple charging cords in the vehicle cabin lead to clutter, inconvenience and distractions.

Safe & Convenient

Freeing drivers from charging cords is not only convenient, it will help create a safer driving experience. The Delphi Wireless Device Charging System is being engineered with consumers and automakers in mind, and will provide a competitive advantage to OEMs who choose to offer it as an option on their future vehicles.

“Our system is being designed to activate the moment a device is detected within the range of the charging pad and will fully charge the device at a rate comparable to most plug-in chargers. What could be more convenient than that?” said Bob Fust, global product line leader, data connectivity, Delphi Packard Electrical/Electronic Architecture. “This innovative development will allow drivers to focus on driving when they are behind the wheel.”

Delphi has a full portfolio of plug-in and wireless charging systems for electric vehicles as well a complete line of data connectivity products including cables, connectors and consumer ports to allow communication of audio, video and navigation data within the vehicle.
