Abstract
The invention provides advances in the arts with useful and novel driver methods. The invention provides circuit driver and control methods for relatively high-current drivers, usable with relatively low-voltage battery power sources. Preferred embodiments include one or more high series resistance capacitors electrically connected with a power source. A low resistance driver circuit regulates power supplied from the capacitors to the load.
