A protective layer is a circuit arrangement that protects other components within a power electronics system from damage caused by abnormal or excessive conditions. It can be implemented in various ways, including using diodes, zener diodes, or ** Schottky diodes** to conduct or block current while preventing the other components from being damaged.
Example: A common application of a protective layer is in MOSFETs. When a MOSFET is conducting current, its gate and source are connected to the same voltage. If a reverse bias is applied to the gate-source connection, the MOSFET is turned off and cannot conduct current further. This helps to prevent the source voltage from exceeding the gate voltage and damaging the MOSFET or the circuit connected to it
