摘要:
A system and method for quickly discharging a DC relay is provided. In one embodiment, the invention relates to circuit for discharging a relay coil, the circuit including a first suppression circuit coupled across a power source, a switch, a relay coil in series with the switch, wherein the relay coil and the switch are coupled across the power source, and a second suppression circuit coupled across the relay coil, wherein the relay coil is configured to actuate at least one load switch when sufficiently energized by the power source, wherein the first suppression circuit is configured to discharge energy stored in the relay coil, and wherein the second suppression circuit is configured to discharge energy stored in the relay coil.
