Importance of free wheeling diode
WitrynaAnswer: Referring to Fig 10.2(b), the free wheeling diode will remain off till ωt = π since the positive load voltage across the load will reverse bias the diode. However, beyond this point as the load voltage tends to become negative the free wheeling diode comes into conduction. The load voltage is clamped to zero there after. As a result Witryna9 kwi 2024 · The term cell denotes either the set of a switch with its antiparallel free-wheeling diode or a simple neutral clamping diode. Note that the cells G-H are only present in the full-bridge topology [20,21,22,23,24,25,26], whereas the cells K-L are only not present in the conventional simplified-bridge topology [15,16,17,18].
