Welcome to the SPRINGBURO website. 

We specialise in the design of custom power electronics, such as Switched Mode Power Supply technology or Motor Control, incorporating latest generation wide band gap devices (e.g. Sic, GaN).

For the last 25 years, we have worked with a variety of Power projects, including custom designs for downhole surveying & drilling, as well as various other industrial power projects requiring high reliability and often exceptional environmental requirements of temperature and vibration. We work with our customers at an early stage to identify suitable topologies and components, which are then prototyped and tested using a full range of in-house test equipment.  An example of the typical processes we are involved in is as follows:

        1) Initial Concepts, Topology, Requirements Capture and Preliminary Design. 
        2) Transformer and Inductor design, specification and manufacture.
        3) Prototyping and Testing including evaluation of design efficiency. 
        4) Full Thermal shutdown and other protection mechanisms.
        5) Thermal design and verification.
        6) Environmental testing.

Once a product design has been completed, we can also offer manufacturing and testing services, so that the fully completed product can be directly delivered to the customer's doorstep.

In addition to this consultancy, Springburo has developed numerous patented technologies for use in the field of Transistor testing and evaluation, such as the "Voltage Clipper" which measures directly at high resolution the real Transistor conduction voltage. This permits the monitoring of power transistor ON-resistances under operating voltages of up to 1500V, as well as the thermal performance during real operating conditions.  More information here.

We  have 2 scope probe calibrators.  One switching 290V in about 2nS, for calibrating 10:1 probes and a high voltage version switching 900V in 5nS.  The calibrators allows easy and accurate  calibration of  scope probes for Power Supply measurements, which is often not possible with the oscilloscopes built in reference calibrator (which often have only 1V output and slow rise and fall times).

With a correctly calibrated scope probe you can determine if the overshoot being measured is real. More information here.
