Abstract
In one embodiment, a method is provided for a power converter system. The method includes: providing a primary current limit for the power converter system, wherein the power converter system has one or more transistors which can be switched on at a primary frequency to cause current to flow through an inductor of the power converter system; and using the primary current limit for over-current protection in the power converter system, wherein over-current protection does not employ any secondary frequency for switching of the one or more transistors and does not employ any secondary current limit.
