Failure Analysis on Pulse Transformers

Failure Analysis on Pulse Transformers

“Gideon Analytical Laboratories received six pulse transformer. Three were good, three were failures. Transformers can be thought of as an electrical component rather than an electronic component. A transformer basically is very simple static (or stationary) electro-magnetic passive electrical device that works to convert electrical energy from one value to another. The transformer does this by linking together two or more electrical circuits using a common oscillating magnetic circuit which is produced by the transformer itself.
Electronic Transformers

Electronic Transformers

Gideon Analytical Laboratories received four electronic transformers, some of which were failing. Three transformers produced no output and the fourth was tested using an oscilloscope and found to function. Transformers are electrical devices typically used to transfer energy between two or more circuits using electromagnetic induction. Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. Using Faraday’s Law with high magnetic permeability core properties, transformers can efficiently change AC voltages from one voltage level to another within a given power network.

Pulse Transformer 144A9111

Gideon Analytical Laboratories received two 144A9111 pulse transformers with the secondary wiring shorting. Transformers are devices that transfer electric energy from one circuit to another, usually with a change in voltage. Pulse transformers are transformers optimized for transmitting rectangular electrical pulses. Ideally, pulse transformer designers try to minimize voltage droop, rise time, and pulse distortion. Small versions called signal types are used in digital logic and telecommunications circuits, often for matching logic drivers to transmission lines.

Failure Analysis on Pulse Transformers

Gideon Analytical Laboratories received six pulse transformers, three of which were failures, three of which were reliable. The objective was to determine the cause of the failures and inspect the unused transformers for anything that could contribute to the cause of failures.
