    Help needed on my First SMPS from scratch (Transformer Calculation)

    I have the need to build a SMPS for my audio amplifier and need to confirm if my calculations for transformer winding are correct.

    Chips used are the SG3525 and IR2110 mosfet driver
    The ferrite...

    Power supply with KA3525

    there is a possibility to increase the output voltage by 10% for a smps with KA3525 when the duty cycle is 49% and I can not change the ratio in the transformer?

    copper tape wrap

    I wrapped the smps switching transformer with a copper tape to reduce the emi. What would you suggest the grounding procedure.
    The tape should be Grounded to DC directly or

    it should be grounded...

    500 Watt Adjustable DC LOAD


    I would like to do some LOAD test for 12V, 24V and 48 Volt SMPS. Is there any Schematic available to build a MOSFET based Adjustable DC LOAD
