摘要
A switch in an inductive circuit is prevented from avalanche operation when the switch is turned off. By preventing avalanche, the associated EMI is reduced or eliminated. Switch avalanche can be prevented using an active component, such as a transistor, or a passive component, such as a resistor, coupled to the switch gate to control current in the switch gate. By controlling current in the switch gate during turn-off, avalanche operation can be prevented without a significant increase in turn-off energy.
