Solenoid Driver Circuit
US Patent:
2007018, Aug 16, 2007
Filed:
Feb 10, 2006
Appl. No.:
11/351508
Inventors:
Stephen Smith - South Lyon MI, US
Subbaraya Radhamohan - Novi MI, US

Subbaraya Radhamohan - Novi MI, US
Thomas Stoltz - Allen Park MI, US
Assignee:
Eaton Corporation - Cleveland OH
International Classification:
H01H 47/32, H01H 47/00
US Classification:
361155000
Abstract:
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.
