Reverse-Current Circuitry Protection
Reverse-Current Circuitry Protection Jan 31, 2001 Battery reversal can be fatal to portable equipment. However, numerous circuits can protect against the backward installation of batteries and other overcurrent-causing conditions. Battery-operated equipment is
Breakdown phenomena in reverse biased silicon solar cells.
Solar cell reverse current-voltage characteristics have been found to vary widely and to be generally unstable. At reverse voltages greater than approximately 20 V and at cell power dissipations of more than 4 W, the probability of permanent breakdown, resulting in cell short-circuit failure, was found to increase with increasing voltage and exposure time. …
