Abstract: A system and method of protecting the input components of a power supply. An input overcurrent protection module is provided, which may be implemented in firmware, which monitors the input current through an input interface of the power supply. When the input current exceeds a threshold current (i.e., a current above the maximum rating of an input component, such as an input cable), the input current protection module determines whether an input overcurrent event is occurring. When it is determined that an input overcurrent event has occurred, the input current protection module disables the output circuitry of the power supply and triggers a few timers. The input overcurrent protection module continues to monitor the input and, if the input current continues to exceed the threshold current, is configured to shut down the power supply. In this way, input components may be protected from overcurrent issues in high-power systems.
