    what should i use as a ac source?

    i have researched how to design and build a flyback converter, most websites use ac as input to the flyback converter. they specify a minimum input voltage and maximum input voltage. what should i use as an ac source?

    most places have some sort of AC power to homes and businesses
    that is likely a good start for power converters about 1 kW (maybe 2 kW) or less

    Re: what should i use as a ac source?

    You are asking about off-line SMPS, which are comprised of a rectifier, a filter capacitor and a flyback converter. Unless you are designing a PFC flyback, you can power it with a DC source as well.

    To test an off-line SMPS with varying input voltage, you can use a variac (variable transformer).

    A variac and an isolating transformer ...
