    hi everyone.

    I have a circuit automatic voltage regulator(AVR) for diesel generator.

    From the image

    Voltage input = 55VAC
    How to use 220VAC without transformer.

    Hello,

    You MUST use a transformer, otherwise the circuit will be UNSAFE.

    Why would you want to do ALL that when a simple transformer will suffice?

    Maybe telling us what you are trying to do would help. (besides getting 55vac from 220vac) A run of the mill 4 to 1 transformer will do the trick.

    If this is your intent, you are mistaken. The diode bridge is an input structure, not some means of making that AC voltage noted as "implementation".

    The AC input clearly requires 55 VAC. The source will be either a special winding or a transformer.

    The circuit is an incomplete AVR, as that PWM input is not described in any way, nor the characteristics of the field winding.

    AVR means? :confused: :confused:
