Switching Power Supply Solar-Array Latchup(2 of 4)

Relevance

This problem illustrates the complexity of problems that occur in powering a constant power load with a current limited source. It also illustrates a controllability problem, that is, the system getting into a state that it can not get out of without outside help. The problem illustrated is a real problem for direct-energy-transfer power systems consisting of a solar-array power source and battery, a constant power load, a shunt power bus regulator, and a battery charger. This configuration is often used in space power systems orbiting the earth.
