Abstract :
Switching-mode DC/DC converters must be protected against overload, to prevent failure of the converter or the external current-carrying hardware. This paper collects, classifies, analyzes, and evaluates the known protection methods, and describes a new negative-feedback frequency modulator which prevents short-circuit-current runaway. Test data prove the effectiveness of the new scheme.
