Abstract
Disclosed is a switch protection circuit and a power converter, configured to set upper and lower limit-value current signals which can be adjusted along with an input voltage, so that instantaneous power of a main power switch can be prevented from being too high, and the main power switch can always be operated within a safe operating range, thereby solving the problem that the power converter is easy to be damaged in applications under a high-current circumstance.
