Abstract:
An adaptive fusing electrical circuit including a power supply and an electrical load comprising:a current detector measuring a current level through the electrical circuit; an interruption switch electrically coupled to the electrical load and said current detector having an open state and a closed state, said interruption switch normally closed; and a controller electrically coupled to the power supply, said current detector, and said switch, said controller monitoring said current level and a first circuit parameter of the electrical circuit; said controller having a first guard band corresponding to said current level and a second guard band corresponding to said first circuit parameter, wherein said controller comparing said current level to said first guard band and said first circuit parameter to said second guard band and switching said interruption switch from said closed state to said open state when said current level is outside said first guard band and said first circuit parameter is outside said second guard band.
