Electronic Relay Circuit Breaker Protects Boost Converter from Short Circuit and Overload

Leave a comment

Boost Converter and Its Unprotected Nature Boost converter topology, where an inductor is alternately shorted to ground by a switching transistor in some portion of the cycle and connected in series with the load in other portion of the cycle, is inherently unprotected from load failures such as short circuit and overload (look at the figure 1 of  the reference […]
