A circuit breaker's function is to cut off the flow of current to an electrical circuit in the case of a fault or surge, preventing overloaded lines, sparks, and fires. Take the humble circuit breaker for example. Every electrical device in the country is connected to the grid through one.
Increasing the circuit breaker opening reaction time by 1 millisecond results in an order of magnitude increase in unwanted current in the system. While the critical purpose of a circuit breaker is to open quickly, the majority of a circuit breaker’s lifetime is spent closed, allowing current to flow normally.
The slow switching speed and short lifecycle of mechanical circuit breakers have led to development of an improved solution - the solid-state circuit breaker. solid-state circuit breaker solves the operating time and arcing problems present in mechanical circuit breakers.
The increased electrification in our society is leading to increased demand on our circuit protection requirements. Circuit breakers are needed in power distribution systems to protect against power surges and short circuits caused by unplanned events such as lighting strikes, downed trees, and equipment failure.
This delay causes high fault currents and electrical arcs which wear the breaker contacts. A potentially superior solution is the solid-state circuit breaker (SSCB), which uses power semiconductors to quickly open a circuit with no moving parts subject to wear.
Since SSCBs do not have mechanical contacts, arcing and its associated risks and countermeasures are eliminated. Additionally, SSCBs allow for a greater degree of control compared to electromechanical circuit breakers. SSCBs can be programmed to open at various current levels based on the differing needs of the system .
