  • High Isolation Flyback Transformer Technical Article
    HIGH ISOLATION VOLTAGE FLYBACK TRANSFORMER By: Edgar C. Taculog Field Application Engineer, Asia TT Electronics New TT Electronics AEC-Q200 qualified and certified transformers are optimized for use with a gate- drive optocoupler to improve and simplify the design of isolated power supplies. Overview Transformers can often provide an inexpensive solution for a variety of applications. The purpose of the transformer is to isolate the secondary side of the circuit from the primary power source, transfer power efficiently from the electrical source to the target load and protect users from hazards like electric shock, fire and heat. The flyback transformer, which is an isolated version of a buck-boost transformer, does not in truth contain a transformer but a coupled inductor arrangement. When the transistor is turned on, current builds up in the primary and energy is stored in the core, this energy is then released to the output circuit through the secondary when the switch is turned off. The basic concept of this scenario can result in significant heat generation if not properly addressed.

  • How to Select a Surge Diode
    Application Report SLVAE37–January 2019 How to select a Surge Diode Alec Forbes ABSTRACT For systems in harsh industrial environments, one of the most important parts of system protection is the input TVS diode selection. The input TVS diode is designed to protect fragile system inputs from large transient spikes that are caused by nearby machinery, lightning strikes, or power surges. These surges are modeled and regulated by IEC 61000-4-5, which standardizes the protection requirements systems must meet in order to ensure that they will not see failures when exposed to these transients. However, passing these standards is not trivial, especially to a designer who is unfamiliar with protection diodes and the specifications. This document will provide an introduction to TVS diodes, comparing them to other transient protection solutions, discussing some of the key specifications and then providing a system example. An understanding of these specifications will allow a designer to have a more solid fundamental understanding of how to select a TVS diode for surge protection, which will directly translate to a more robust system.

Antonescu, NRC Project Manager Prepared for Division of Engineering Technology Office of Nuclear Regulatory Research U.S. Nuclear Regulatory Commission Washington, DC 20555-0001 NRC Job Code Y6272 ABSTRACT This document presents recommendations and the associated technical basis for addressing the effects of conducted electromagnetic interference (EMI) and radio-frequency interference (RFI) along interconnecting signal lines in safety-related instrumentation and control (I&C) systems. Oak Ridge National Laboratory has been engaged in assisting the U.S. Nuclear Regulatory Commission Office of Nuclear Regulatory Research in developing the technical basis for regulatory guidance on EMI/RFI immunity and power surge withstand capability (SWC). Previous research efforts have provided recommendations on (1) electromagnetic compatibility design and installation practices, (2) the endorsement of EMI/RFI and SWC test criteria and test methods, (3) the determination of ambient electromagnetic conditions at nuclear power plants, and (4) the development of recommended electromagnetic operating envelopes applicable to locations where safety-related I&C systems will be installed. The current research focuses on the susceptibility of I&C systems to conducted EMI/RFI along interconnecting signal lines.
