  • Transformer Design for Charging Defibrillator Capacitors
    ancient technology now, was the flyback. transformer in color televisions with a CRT. These transformers could generate voltages. greater than 35,000 volts. Voltages so high that if the circuits malfunctioned, the television. could generate damaging X-rays. The analysis is somewhat simplified because
  • Which High-Frequency Power Switchmode Transformer is Right For Your Application
    designs are used extensively in high frequency electronic applications, usually within a switchmode power supply. Common transformer configurations include Flyback Transformers, High Frequency Transformers and Push-Pull Transformers. Precision, Inc, a specialist in custom and standard magnetic design
  • Switch Mode Power Supplies and their Magnetics
    of magnetic. are two types of Flyback circuits — continuous mode and. components that are needed for the typical SMPS. They. discontinuous. The continuous mode is primarily used at. include the Output Transformer, usually the most noticeable. power levels up to 250 W and discontinuous up to about
  • Common Power Supply Topologies
    elements until the start of the next cycle. Adding a transformer to the basic circuit adds some important advantages. When the input is 120 or 230 VAC, the. transformer provides isolation. It also allows the input voltage to the buck circuit to be matched to the required. output voltage and multiple
  • Offline LED Driver Intended for ENERGY STAR (R) Residential LED Luminaire Applications

High power factor requires generally sinusoidal line. sine-squared shape. The flyback transformer must couple. current and minimal phase displacement between the line
  • Magnetic Component Alternate Sourcing Strategies
    Due to the complexities of circuit design and the highly customizable nature of magnetic components, such as transformers and inductors, they are often overlooked by OEMs when it comes to alternate or second source strategies. Magnetic components can be difficult to specify in the first place
  • Testing Transient Responce In DC/DC Converters
    with no isolation. Figure 1 below shows typical delay times of an optically-isolated flyback converter. The total propagation delay in the feedback loop is the sum of all delays of the components used in the feedback loop. ./19d641a9-48c5-44dd-9896-3de290f41722 beta. Application Note DC-001. dyne. DC
