ABSTRACT:
A regulator which shunts excess current from a solar cell array in which zener diodes of different values are used to separate the control signal into divisions. The control signal, now divided, is used to separate array current into divisions. Each of the divisions of current is shunted by a separate power transistor stage, which is active only over a limited portion of the entire current range. The advantage of having each of the power stages active only over a particular range is to reduce the power dissipation in the shunt regulator by a significant amount and thereby allow greater mechanical design flexibility and lower overall weight.
