Hey, though I appreciate this post and have given it a steemstem upvote, it comes very close to plagiarism at points. For example:

A basic switching converter consists of power switching stage and the control circuit. Power conversion from the input voltage to the output voltage is made possible by the power switching stage while the control circuit controls the turning Off and On (duty cycle) of the switching device.

Original

The basic switching converter consists of a power switching stage and a control circuit. The power switching stage performs the power conversion from the circuits input voltage, VIN to its output voltage, VOUT which includes output filtering.

My advice to avoid being blacklisted is to try and be a bit more creative and original with your content rather than just re-writing information from some websites, which is the feeling I get from this post.

The more original a post is the better rewarded it gets and the more interesting it is to the readers.

Good luck
