Claim 12:
13. The apparatus of claim 11 further comprising:
one or more smart dual switching (“SDS”) devices, each including SDS circuitry in an SDS package constructed and arranged as a self-contained electronic switching device, the SDS package having a common terminal, a first switched terminal, and a second switched terminal;
the SDS circuitry including:
a first electronic switch having a first control terminal, a first switched terminal, and a first common terminal,
a second electronic switch having a second control terminal, a second switched terminal, and a second common terminal,
a first SDS control circuit having an input connected to the first switched terminal, an input connected to the second switched terminal, and an output connected to the first control terminal, the first SDS control circuit being adapted to turn the first electronic switch OFF in any of three conditions:
(i) while the second electronic switch is ON; or
(ii) if the polarity of the voltage across the first electronic switch is of a first pre-determined polarity, when the magnitude of the voltage across the first electronic switch is at a first pre-determined threshold; or
(iii) if the polarity of the voltage across the first electronic switch is of the opposite polarity, after the first switch has been ON for a first pre-determined period of time; and

a second SDS control circuit having an input connected to the first switched terminal, an input connected to the second switched terminal, and an output connected to the second control terminal, the second SDS control circuit being adapted to turn the second electronic switch OFF in any of three conditions:
(i) while the first electronic switch is ON; or
(ii) if the polarity of the voltage across the second electronic switch is of a first pre-determined polarity, when the magnitude of the voltage across the second electronic switch is at a second pre-determined threshold; or
(iii) if the polarity of the voltage across the second electronic switch is of the opposite polarity, after the second switch has been ON for a second pre-determined period of time; and

wherein the switch of each of the plurality of cell elements comprises a respective electronic switch in a respective SDS device.
