    Constant current in SMPS

    So then the difference between the two is that in current mode, the current is more important in the equation (basically limiting the maximum current),

    Constant current in SMPS

    @Bogdan2011
    In the chip used if it has a current sense comparator then to lower the current the voltage has to be reduced. There is no way to reduce

    Constant current in SMPS

    Greetings,
    I'm building a variable lab power supply and I'm trying to understand how constant current / current feedback works with PWM.

    Half Bridge vs Full bridge SMPS

    @Robson132
    Well in theory half bridge is suitable up to 500w but I got 1200 out of a half bridge smps. I think if you use half bridge is well suited

    Half Bridge vs Full bridge SMPS

    Hi.
    The subject of my engineering work is the design of smps 500W for audio amplifier.
    I do not know what to choose topology (half vs full

    ETD29 Winding Advice Needed

    Thanks Silvio,

    Yes will likely proto up the inverter to see how it will work, but will create the schematic so I can at something to build

    ETD29 Winding Advice Needed

    Hi Sandy.
    Regarding the transformer primary if using 60Khz then 0,5mm wire is suitable for your trafo as this can go to a maximum of 68Khz. Your

    Silvio -

    It's going to be used for an automotive ignition system (multi-spark CDI). The basic use of the the transformer will be for a DC-DC

    One thing you did not mention was the total power of the inverter you are building, perhaps we can help you in the wire size you need. You can tell us
