  Flyback converter without IC<\/h2>\n\n\n\n

  :<\/strong>Description<\/h2>\n\n\n\n

  The 48 watt self-oscillating power supply (RCC) or Ringing choke converter was one of the projects that was built according to the market’s needs. The design of this circuit requires a deep understanding of the function of electronic components, analog circuits, as well as a complete mastery of the flyback topology.
  Because of the Corona crisis, the reopening of factories after vaccination, the increase in demand for electronic devices, the impact on the supply cycle of raw materials for semiconductor manufacturers, and the trade war between China and the United States, etc. ; The inventory of the raw materials for the production of generators was threatened and their prices increased; We decided to design a circuit that is designed with more common and general parts so that it can work with both MOSFET and BGT without any IC, as if we are in the 90s.<\/p>\n\n\n\n

  :<\/strong>Specifications<\/h2>\n\n\n\n

  Input voltage: 90VAC-250VAC
  Output voltage: 12V\/4A
  Switching frequency (depending on the load): 33Khz-90Khz
  Load regulation: 2%
  Line regulation: 2%
  Efficiency: 78-84%

  The transformer and current limiter in this circuit are responsible for the oscillation, the feedback is applied to the primary part by IC TL431 and optocoupler. First, it puts a switch resistor in conduction mode, after the current passes through the transformer, the switch will be completely turned on by the paired coil, when the current peak reaches the set limit, the switch is cut off and this cycle is continuously repeated until the switching operation is completed. to be<\/p>\n","protected":false},"excerpt":{"rendered":"
