WitrynaHere catch diode is used to eliminate flyback, when the abrupt voltage spike is witnessed across the inductive load when the supply current abruptly reduced. It helps the circuit from damaging. It will get … 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

This results in benefits such as a simplified mechanical stack construction with series stacking of press-pack IGBTs and freewheeling diodes. In addition, a time saving of 50% in stack design, fewer safety devices required thanks … WitrynaForward-biased diodes are not perfectly conductive; there is a voltage drop of 0.7V (0.3V for Schottky) across them. At high currents, this results in high power dissipation across the diode. High-current diodes may have longer recovery time too. When the lower MOSFET is on, current flows through it rather than the body diode.
