  • White Paper: Comparing Transformer-free to Transformer-based UPS Designs
    is in their respective use of transformers. A transformer-based UPS may use a transformer before the rectifier and requires an isolation transformer after. the inverter to derive the voltage being delivered to the critical load. Transformer-free UPS designs use power. and control electronics technologies
  • Wideband Transformers
    winding resistances and loss. transmission characteristics of the transformer. less magnetic materials. North Hills designs and manufactures a wide variety of. wideband transformers in unbalanced to unbalanced,. Input and output powers wil , therefore, be equal in an. balun, i.e. unbalanced
  • Comparative Test of Low Voltage Lighting Transformers
    Landscape Lighting transformers differ greatly in design, construction and performance. To demonstrate the importance of these differences, a team of electrical engineers were asked to compare two transformers that are commonly used in Landscape Lighting installations. The transformers used
  • Transformer Design for Charging Defibrillator Capacitors
    . A number of. variables in circuit design, layout, transformer design, components, etc., will effect the result. (For very high voltage designs, even the leakage current paths across the surface of the PC. board and leakage within the capacitor must be considered.). MAXIMUM. EFFICIENCY. EFFICIENCY
  • Current-Sense Transformer Application Design Guidelines
    . transformer. They are accurate, easy to. Set Output Voltage. implement, and reliable under harsh. environmental and thermal conditions. In. electronic systems applications such as. Choose Turns Ratio /. switch-mode power supplies, current. Transformer Package. transformers are generally used for. control
  • Linear Variable Differential Transformer Technology
    Differential transformers are electromagnetic devices for translating the displacement of a magnetic armature into an AC voltage, which is a linear function of the displacement. They are basically composed of primary and secondary coils wound on an air core and a movable armature is used to control
  • Technical Article: The Ferroresonant Transformer Voltage Regulator
    The ferroresonant transformer or constant voltage transformer has a very long history having been invented in 1938 by Joseph Sola and continuing to sell tens of thousands of units per year. The ferro of today has had some minor improvements but remains fundamentally unchanged from the original
  • Design Optimization Of Linear Transformer Driver (LTD) Stage Cell Capacitors (.pdf)
    . INTRODUCTION. verify models in the time domain, measurements were. also made by using high voltage discharge of the. This work is part of a SNL sponsored effort to capacitor into a resistive load. evaluate the possibility of improving Linear Transformer. Driver (LTD) performance by optimizing the design
  • Current Chopping a Simple Explanation, and Calculations to Determine Transient Voltages When Using Vacuum Interrupters
