Although solid-state circuit breakers have multiple advantages compared to mechanical circuit breakers, they also have some drawbacks, including limited voltage/current ratings, higher conduction losses, and higher prices for F7131. Typically, for AC applications, solid-state circuit breakers are based on thyristor rectifiers (TRIAC), while for DC systems, they are based on standard planar MOSFETs. Triac or MOSFET is responsible for implementing the switching function, while photoisolated drivers are used as control components. However, in the case of high output current, MOSFET based high current solid-state circuit breakers require the use of heat sinks, which means they cannot achieve the same power density level as mechanical circuit breakers.

Similarly, solid-state circuit breakers implemented with insulated gate bipolar transistors (IGBT) using F7131 also require heat sinks, as saturation voltage can cause excessive power loss when the current exceeds several tens of amperes. For example, when the current is 500 amperes, a 2V voltage drop across the IGBT can result in a power loss of up to 1000W. For the same power level, MOSFET needs to have approximately 4 meters? The conductivity resistance. As the voltage rating of components in electric vehicles develops towards 800V (or even higher), there is currently no single component that can achieve this resistance level. Although theoretically multiple devices can be connected in parallel to achieve this number, this approach significantly increases the size and cost of the solution, especially when dealing with bidirectional currents.
