  We present an experimentally realizable stabilized charge pumping scheme in a
linear array of Cooper-pair boxes. The system design intrinsically protects the
pumping mechanism from severe errors, especially current reversal and
spontaneous charge excitation. The quantum Zeno effect is implemented to
further diminish pumping errors. The characteristics of this scheme are
considered from the perspective of improving the current standard. Such an
improvement bears relevence to the closure of the so-called measurement
triangle (see D. Averin [Nature 434, 285 (2005)]).
