    Hi, everyone. I am currently doing a power supply research for my final year project but I found out that a transformer would not be able to produce a sinusoidal secondary voltage while it is connected onto a load.

    The transformer that i used is a Myra 45059. The voltage waveform was taken by a Tektronix TPS 2014. A load will be connected to a load which draw 0.52 A. Please refer to the datasheet provided and the voltage output that I have provided. The voltage for CH1 is the voltage output from the secondary of the step down transformer. Thank you.

    Please post the complete circuit diagram and where the voltages were measured.
    How is the primary wired?
