Power Loss Down by Half with GE Energy’s DC-DC Converter

August 02, 2011 / William Thomson, Green Homes Expert

GE Energy (NYSE: GE) Power Electronics has released the Lineage Power Hammerhead Series of industrial DC-DC converter, offering a wide input voltage range from 18 to 75 Vdc with Total Efficiency architecture technology that reduces power loss up to 50 percent.

Power Loss Down by Half with GE Energy’s DC-DC Converter

Designed for extreme temperature conditions of -40°C to +85°C, the cost-effective Hammerhead DC-DC converter is designed to resist extreme temperature conditions of -40°C to +85°C.

The green product was released on the heels of a deal between GE Energy and Wind Capital Group involving 228 wind turbines and the accompanying operations and maintenance services for projects in Oklahoma and Kansas. The projects are expected to provide more than 350 megawatts of reliable, clean renewable energy for the Midwestern United States and create jobs and economic stimulus for local landowners and surrounding communities.

Hammerhead DC-DC isolated converters help OEM design engineers achieve electrical isolation, increase device reliability and accelerate new product introduction across medical, military and other industrial applications. The standards-based DOSA footprints and compatibility with existing circuit board designs shrinks the size, lowers the cost and improves the performance of board-mounted power modules.

“The flexible Hammerhead DC-DC converter modules are technology leaders in efficiency and performance,” said Niklas Fallgren, vice president and general manager of OEM Embedded Power at GE Energy.

“These board mounted power modules are designed for use in a wide variety of industrial applications to give power design engineers a reliable solution that lowers cost and reduces risk when compared to other power solutions.”

The new Hammerhead modules are available in eighth-brick Distributed-power Open Standards Alliance (DOSA) standard footprints with three output models rated for 12 Volts @ 6 Amps, 5 Volts @ 15 Amps or 3.3 Volts @ 20 Amps.

DOSA was formed to further forward DC-DC product compatibility and standardization within the fragmented power converter market. Alliance members include founding members Lineage Power and SynQor as well as AcBel, Bel Power, CUI, Delta Electronics, Emerson Network Power, Ericsson Power Modules, FDK, Lucky Valley Technology, Murata Power Solutions, NetPower Technologies, Power-One, TDK-Lambda and Wall Industries.

Hammerhead leverages the Bell Labs heritage for reliability and quality. At the same time it uses the latest component technologies and process techniques to accelerate adoption through competitive value engineering savings opportunities. Its wide input and operating temperature range is ideal for use in robotics, test and measurement equipment, medical devices, navigation systems, automotive electronics and cellular infrastructure devices.

The open frame module construction, available in both surface-mount and through-hole packages, enables design engineers to minimize circuit board real estate usage, while ensuring DOSA footprint compatibility.

All Hammerhead modules achieve typical, full-load efficiency greater than 92 percent at VIN=24Vdc and greater than 90 percent at VIN=48Vdc. Standard features include remote on/off, remote sense, output voltage adjustment, over-voltage, over-current and over-temperature protection.

An optional heat plate allows for external, standard eighth-brick heat sink attachment to achieve higher output current in extreme temperature environments.
