    Control algorithm contains PI regulator.
    hardware contains H-bridge inverter.
    (1) when resistive load is connected at inverter output terminals, Sine shape retains(which is expected.)
    (2) When i am connecting Transformer to boost current from 0.5A to 5A, sine shape convert to something like bell shape.
    how to overcome this issue?

    Another post full of information. PI proportional/integral?
    PWM sine?

    Or possibly because another transfomer is connected to an inverter, it's an even worse modified sine wave than just the inverters modified sine wave.
