Summary:A solenoid drive circuit includes a boost energy storage device, such as a capacitor, that captures energy from and discharges energy to a solenoid. Switches control the connection between the boost device, the solenoid, and a power source. This allows the solenoid response time to be variable based on the characteristics of the boost device as well as the solenoid. By providing two different solenoid current rise and decay rates and by capturing and re-using energy stored in the solenoid, the inventive drive circuit enhances solenoid response and increases efficiency.
