  • Isolation Transformers Increase Safety of Electronic Systems (.pdf)
    Adequate isolation between a power source and a user of electronic equipment ensures the safety of that equipment. Given the high voltages that exist in modern electronic equipment, proper isolation protects an operator from contact with excessive electrical energy should a short circuit occur
  • High-Voltage ICs
    isolation between transistors, whichever is most restrictive. The ICs are fabricated on low-resistivity silicon wafers to reduce power loss and improve device speed. Wafer resistivity is lowered by heavy doping. But junctions formed in heavily doped material have low breakdown voltages. High-voltage
  • High-five to high-side current sensing
    through the meter. The technique was called high-side current sensing. However, high-side shunts require isolation in modern electronic control systems because of their direct connection to the high-side voltage rail. Current transformers perform this service in ac power systems. But the size and cost
  • Transformer Design for Charging Defibrillator Capacitors
    several advantages - 1) Simple circuit. 2) High voltage output is not dependent on large turns ratios. 3) Circuit is self limiting. Output can be shorted without damage. 4) Output can be regulated over a large range. 5) Transformer can provide voltage isolation. 6) Multiple isolated outputs
  • Circuit Ideas: High-efficiency dc/dc conversion
    connected to the primary of an isolation transformer. High efficiency comes from careful choice of the C value and use of fast synchronous rectifier drive circuitry. An example is the converter shown in the accompanying diagram which delivers 3.3 V at 30 A from a 48-V source with over 92% efficiency
  • High Speed and Safety Reinforced Digital Isolator for Endoscope and Medical Imaging Applications
    isolation so the sensor won't shock the. patient. The combination of high speed and stringent safety requirements. presents signifi cant challenges to isolation. design and often resulted in expensive solution, e.g. fi ber optics. With latest transformer on fl ex technology. developed by Avago
  • Technical Article: Ferroresonant Transformer Advantages & Disadvantages
    The ferro voltage regulator, by its unique design, provides good isolation of load equipment from line noise and surges. The output voltage regulation is also smooth so long as the manufacturer has taken steps to minimize the distortion that is caused by operation in the saturation region. Ferro
  • Active and Passive Isolators
    Alternating voltages and alternating currents can easily be transmitted and electrically isolated using transformers. Transformers are reliable, easy to produce and suitable for high working voltages (isolation voltages) when configured accordingly. The transformers are not suitable
