    This AC to DC converter circuit is capable of converting an alternative voltage within 70V – 260V range into a DC voltage within 180V to 350V DC range, so it can be used for 110V and 220V too. To achieve this voltage conversion we use a MC34161 rectifier as a voltage doubler at low input voltages and as a classic rectifier at high input voltages.

    MC34161 includes a reference power supply which delivers 2.54V at pin 1. The signal level applied at pin 2 is internally compared with a 1.27V voltage.
    D5 zener diode, togheter with R1 and C4 provide IC’s required 12V voltage. Capacitor’s voltage of C2 and C3 must be greater than 250V.

    Attention: this ac to dc converter contains very high voltages that are deadly and you must be very careful!

      may someone please explain the operation of the circuit, especially the purposes of resistors R7 & R8 and capacitors C2 & C3

    4. Hi,
      Can I replace the IC MC34161 and TRI TIC216 with other IC and TRI?
      Because it’s hard to get in my country….

    5. pleas ,i want a circuit from led driver 150w

    6. Can u please let me know why we have to convert Ac to dc. why we cannot use dc power 12v or 24v, etc directly for appliances which can reduce cost.

    7. I want to make a AC to DC converter

    8. Hi

      I need help with design of a combination of solar and AC charger.

      Regards;

    9. Sir is it possible to convert 230v ac to 3kv dc…

    10. I need 1kv Dc from 230ac voltage..
