Looking for documentation about power electronics
This topology is known as an Asymmetric bridge. It is useful when you only need unidirectional current but also must manage a free-wheel path. The classic use of this is in Switch-Reluctance drives or induction heating

You need to turn both switches on to build up current. You then have two additional states available to you.

Turn both switches off. This exposes the coil to a negative voltage loop which will cause the current to decay quickly
Turn bottom switch off. This exposes the coil to a zero voltage loop as the current freewheel via to the top diode and the top switch. This reduces current ripple.


Typically the zero-volt loop method is used during an SR sector then switching to negative to decay for next phase
