Go learn some basic electronics! You apparently don't understand basic electronics nor basic logic. You should take your own advice. In the above circuit, opening the switch will simply turn it into a spark gap, across which current continues to flow. You cannot instantaneously change the current through an inductor.
It WILL maintain its current, regardless of how much resistance you put in the way. More resistance just means a higher voltage; as high as is necessary to preserve the current, even if that means vapourising the "switch". You fucking morons supprise me every day I would explain it but what's the use.
But if I don't explain it you and others will just say I don't know what I'm talking about. That so called spark isn't going to last long enough to make much of a difference.
Also inductors tend to have snubbers to prevent that so the switch's are not ruined PWM is not "about peak current vs average current", not in a context where you can call the load an inductor.
There is a reason why everyone is jumping on you! And the catch diode or "snubber" is essential to this process, it it not just a detail.
That simply is not true. If the switch did not fully turn off then it is not switching and would be working in the linear mode assuming a mosfet.
That means high power dissipation. It might be true that for an inductive load the switch doesn't turn off as sharply but that is irrelevant for the point of the discussion which no one in this group cared to follow which is not just the post that Phil "FUCKWIT" Allison posted but a who thread in another group.
If the switching frequency is fast then the effects of the transitions due come into play more obviously because they take up more time in the cycle than for long periods but that is a non-ideal case when the discussion was about how PWM worked. But as usual people want to take stuff out of context so they can act intelligent.
Your a fucking moron. If you actually cared to read what was posted you might be able to pass middle school. VCC switch inductor GND Your telling me when the switch is open that current is flowing through the inductor!!! But these guys think it that knowing an an inductor tries to keep the current through it from changing known as faradays law is some expert knowledge.Abstract This report is the basis for a Bachelor of Science thesis in engineering done at Volvo Powertrain in Gothenburg.

In this thesis, three di erent three-level space vector PWM switching sequences are applied to a three-level neutral- point-clamped (NPC) inverter driving an internal permanent magnet (IPM) machine.
This project is focus on modeling and simulation of single phase inverter as a frequency changer modulated by Sinusoidal Pulse Width Modulation (SPWM). An inverter is a circuit that converts DC sources to AC sources. Pulse Width Modulation is a technique that use as a way to decrease total harmonic distortion in inverter circuit.
