The approach described in this application note from Linear Technology uses four DC/DC µmodule regulators in parallel to increase output current while sharing the current equally among each device. This solution relies on the accurate current sharing of the µmodule regulators to prevent hotspots by dissipating the heat evenly over a compact surface area. The solution casts no thermal shadow on its surrounding components, further optimising thermal performance of the entire system.
In a recent discussion with a system designer, the requirement for his power supply was to regulate 1.5V and deliver up to 40A of current to a load that consisted of four FPGAs. This is up to 60W of power that must be delivered in a small area with the lowest height profile possible to allow a steady flow of air for cooling. The power supply had to be surface mountable and operate at high enough efficiency to minimise heat dissipation. Such a solution requires an innovative design, ...
Photomultipliers (PMTs), avalanche photodiodes (APDs), ultrasonic transducers, capacitance microphones, radiation detectors and similar devices require high-voltage, low-current bias. Additionally, the high voltage must be pristinely free of noise. This application note from Linear Technology describes a variety of circuits featuring outputs from 200V to 1,000V with output noise below 100µV measured in a 100MHz bandwidth.
This application note forms Linear Technology’s eighth circuit collection publication. Topics include a JFET-based DC/DC converter powered from 300mV supply; a bipolar transistor-based 550mV input DC/DC converter; a floating output, variable potential battery simulator; and more.
Automobiles, aircraft, marine vehicles, uninterruptible power supplies and telecommunications hardware represent areas utilising series-connected battery stacks. These stacks of individual cells may contain many units. In such systems, it is often desirable to accurately determine each individual cell’s voltage. Obtaining this information in the presence of the high ‘common-mode’ voltage generated by the battery stack is more difficult than might be supposed.
In this white paper, Jim Wallace, associate director of the Seaward Group, offers an overview of the in-service inspection and testing of electrical equipment and appliances. It is doubtful whether any single issue has raised as much discussion and debate in the electrical services industry as that provoked by portable appliance testing.
Before the IEC 62310, prior to 2008, there was no product standard for the ‘static transfer system’ (STS). The closest standard used by manufacturers was the IEC 62040 (uninterruptible power systems, or UPSs). Indeed it is a good reference, but the weak points are definitions and tests. This paper from Socomec explains why users should ask for IEC 62310-compliant STSs.
As this technical guide from Socomec UPS explains, an RS485 bus is defined by the standard EIA-TIA-485-A and the TSB-89-A application guidelines. A RS485 transceiver is from a standard point of view connected through three points on the network.
