Minimization of solar cell hot-spots on GPS solar arrays using SABER modeling

摘要: The GPS Block IIR solar array originally was designed with circuits consisting of 160 4/spl times/6 cm. silicon cells connected as 2 in parallel 80 series. Because each cell the 2/spl times/80 there a concern that severe hot spot heating individual could occur under shadowing conditions. An analog model developed to simulate operation order better implications this condition. A number different circuit topologies were simulated reduce heating. Eliminating connections between found be best way minimize without resorting bypass diodes.
