Systems and methods for controlling contactor bounce

A non-transitory computer-readable medium comprising computer-executable instructions that, when executed, are configured to cause at least one processor to perform operations comprising:

• sending a first signal to a first switch, wherein the first signal is configured to cause the first switch to close in response to receiving the first signal, thereby electrically coupling a power source to a coil, and wherein the first signal is sent in response to detecting a fault condition, wherein the coil is configured to receive a voltage output via the power source, wherein the voltage output is configured to energize the coil, thereby causing an armature to move from a first position to a second position;
• sending a second signal to a second switch, wherein the second signal is configured to cause the second switch to open in response to detecting that the coil is being energized, thereby electrically coupling an inductor to the coil, and wherein the inductor is configured to reduce a speed in which the armature moves from the first position to the second position;
• determining a change in the speed corresponding to the armature moving from the first position to the second position as compared to a previous move from the first position to the second position;
• and
• adjusting a time in which the second signal is sent to the second switch in a subsequent fault detection operation in response to the speed changing.

A method, comprising:

• sending, via a circuit, a first signal to a first switch configured to couple a coil to a power source, wherein the first signal is configured to cause the first switch to close in response to receiving the first signal, and wherein the first signal is sent in response to detecting a fault condition, wherein the coil is configured to receive a voltage output via the power source, wherein the voltage output is configured to energize the coil, thereby causing an armature to move from a first position to a second position;
• transmitting, via the circuit, at least one pulse of current from the power source to the coil;
• sending, via the circuit, a second signal to a second switch configured to couple the coil to an inductor, wherein the second signal is configured to cause the second switch to open in response to detecting that the coil is energized, wherein the inductor is configured to reduce a speed in which the armature moves from the first position to the second position;
• transmitting, via the circuit, current from the power source to the coil after the at least one pulse of current, wherein the at least one pulse of current is configured to energize the coil thereby causing an armature to move from a first position to a second position, and wherein the current is transmitted to the coil before the armature moves to the second position
• determining, via the circuit, a change in the speed corresponding to the armature moving from the first position to the second position as compared to a previous move from the first position to the second position;
• and
• adjusting, via the circuit, a time in which the second signal is sent to the second switch in a subsequent fault detection operation in response to the speed changing.
