US Patent:

7009370, Mar 7, 2006

Filed:

Jul 1, 2005

Appl. No.:

11/174368

Inventors:

Donald Joe Deaton - Huntsville AL, US

Assignee:

DRS Test & Energy Management, Inc. - Huntsville AL

International Classification:

G05F 1/59

US Classification:

323272

Abstract:

A scalable, interleaved pulse forming converter is disclosed having two Buck switching converter modules each contributing half to the total load of the circuit to produce a programmable current pulse. Synchronization pulses to the two modules are set 180 degrees out of phase of each other to reduce ripple current. The invention is susceptible to various interleaved modifications to further reduce ripple current and increase power, as well as to electrically isolate the load from input or battery ground.

US Classification:

244 1TD

Abstract:

A reeling control system and an air driven tow reel machine incorporating such a control system are disclosed. In the disclosed control system and reeling machine of the present invention, towline velocity is monitored and reel-in and reel-out operations are regulated according to a programmed towline velocity profile. A position sensor senses the position of the turbine vent doors and a velocity sensor device provides the instantaneous towline velocity. A velocity comparator compares the instantaneous towline velocity with a desired velocity value from a desired velocity profile. Based upon the difference between actual and desired towline velocities, a door control device generates a driving signal for controlling the vent door position accordingly.
