Roadside Variable Message Signs

Traffic variable message signs are subjected to all the elements of weather. TDK-Lambda’s 50W and 150W HWS-A series of power supplies was selected by one sign manufacturer not only for having a limited lifetime warranty, but by using the /HD models, the product is guaranteed to start up at -40oC.

New Power Supply Heatsink Construction Patent


TDK Corporation announces that TDK-Lambda UK’s power supply heat-sink arrangement patent application has been approved by the UK Intellectual Property Office.

Power supplies designers utilise a variety of components that dissipate heat, including leaded (through hole) and surface mount devices. These parts, however, require different cooling arrangements.

Surface mount power devices can be mounted on an insulated metal substrate (IMS) consisting of layers of copper traces and thermally conductive insulation bonded to a metal baseplate. This substrate is usually vertically mounted and electrically connected to the main circuit board with a lead-frame.

Although power semiconductors are available in surface mount packages, it is easier to transfer high currents to the main board with a leaded part. This alleviates the need for multiple low current pins on the lead-frame, occupying valuable board area. Conversely leaded parts require fasteners and insulation to mount them to a heatsink. Surface mount I2PAK packages with leads to carry the high currents to the main board are available, but are expensive. Consequently, a combination of both surface mount and leaded components are generally required.

“Available space and electrical clearance was an issue,” Martin Coates Senior Electrical Design Engineer, TDK-Lambda explained. “We needed a cost effective hybrid solution.”

The heat-sink arrangement developed by TDK-Lambda utilises a traditional IMS board
containing surface mounted power components on one side. Leaded power semiconductors are attached to the other side with a double-sided adhesive tape with both insulating and thermally conductive properties. The completed space saving assembly does not use any mechanical fasteners and can be easily soldered to the main circuit board.

Laser for Medical Device Manufacturing

The use of lasers to machine parts is now a tried and true process. For small precision medical devices like stents, the laser is pulsed to reduce heat for durations that are measured in picoseconds. The half rack Genesys™ 12.5V 60A programmable power supply with LAN interface was picked for its ability to deliver tightly regulated power under pulsed loading conditions.

High Current Semiconductor Reliability Tester

Genesys™ Programmable Power Supply

Although the technical specifications of a programmable power supply are paramount for semiconductor reliability testing, particularly when high currents are needed, a manufacturer chose the Genesys™ series for aesthetic reasons. TDK-Lambda was able to produce the power supply with a special colour front panel to match their equipment.

Traffic Control Systems

HFE Front End Power supply

Marine and air traffic can be monitored and controlled utilising their radio transmissions, which is digitally processed and then portrayed in a format similar to a radar screen. One manufacturer of such a system is using the 1600W HFE power supply due to its compact size and the reputation of TDK-Lambda.
