In case of class B commutation or resonant-pulse commutation with L = ...
In the case of class B commutation or resonant-pulse commutation with an inductance value (L) of 5, the commutation process involves switching off the current flowing through the inductor at a point where the voltage across the inductor is zero. This is done by using a resonant circuit or pulse generator to create a high-frequency pulse that causes the current to flow in the opposite direction, effectively turning off the current.

The resonant circuit or pulse generator is designed to provide a high-frequency pulse that matches the resonance frequency of the inductor. When the pulse is applied to the inductor, it quickly reduces the current to zero, thus achieving the commutation process.

The use of class B commutation or resonant-pulse commutation with an inductance value of 5 allows for efficient and controlled switching of the current flow through the inductor. This type of commutation technique is commonly used in power electronics applications, such as in switching power supplies and motor control circuits.
