Hi,
What is hard switching?
Google only refers to some documents.
But can someone expalain it in a short definition?
Thank you in advance!

Hard switching occurs when there is an overlap between voltage and current when switching the transistor on and off.
This overlap causes energy loss which can be minimized by increasing the di/dt and dv/dt.
However, fast changing di/dt or dv/dt causes EMI to be generated. Therefore the di/dt and dv/dt should be optimized to avoid EMI issues.
