| 摘要 | A drive circuit for a DC latching device includes a battery, a storage element, and a plurality of switches connecting the battery to the storage element for charging the storage element from the battery and discharging the storage element into the coil of a DC latching device. The drive circuit further includes components for determining a state of the DC latching device. The drive circuit may include components for terminating the discharge of the storage element into the coil of the DC latching device in response to determining that the DC latching device has changed states to add reliability to the system and reduce energy consumption. | ||||||
