Abstract
A technique for driving one or more EEFLs, having first and second ends, in a bank of EEFLs involves driving the EEFLs at both the first and second ends. In a non-limiting embodiment a device constructed according to the technique includes a bank of EEFLs connected in parallel. The device further includes a first transformer, wherein a secondary winding of the first transformer is coupled to the first end of the bank of EEFLs. The device further includes a second transformer, wherein a secondary winding of the second transformer is coupled to the second end of the bank of EEFLs.
