When the power supply is abruptly interrupted, it produces a excessive voltage in most inductive hundreds. However, you probably can defend costly tools by connecting a diode throughout the inductive hundreds. Depending on the kind of security, these diodes are recognized by many names including snubber diode, flyback diode, suppression diode, and freewheeling diode, amongst others. The commonest and important utility of a diode is the rectification of AC power to DC energy. Usually, a half-wave or a full-wave rectifier is used to transform AC energy into DC power, notably in household energy supply.
