Abstract:
Systems and methods are provided for protecting a power conversion system. A system controller includes a first controller terminal and a second controller terminal. The first controller terminal is configured to provide a drive signal to close and open a switch to affect a first current flowing through a primary winding of a power conversion system. The second controller terminal is configured to receive first input signals during one or more first switching periods and receive second input signals during one or more second switching periods. The system controller is configured to determine whether a temperature associated with the power conversion system is larger than a predetermined temperature threshold, and in response to the temperature associated with the power conversion system being larger than the predetermined temperature threshold, generate the drive signal to cause the switch open and remain open to protect the power conversion system.

Claim (Index 61):
A system controller for protecting a power converter, the system controller comprising:\n a protection signal generator configured to receive a first voltage signal associated with a first input current flowing through a resistor during a first switching period and receive a second voltage signal associated with a second input current flowing through the resistor during a second switching period; wherein the protection signal generator is further configured to, in response to the first voltage signal minus the second voltage signal being smaller than a predetermined threshold in magnitude, generate a protection signal for a switch of a power converter to open and remain open; wherein the first switching period precedes the second switching period; wherein:\n the first input current is not equal to zero in magnitude; and \n the second input current is not equal to zero in magnitude; \n wherein the first voltage signal minus the second voltage signal is proportional to the first input current minus the second input current.
