| Summary: | 碩士 === 國立中正大學 === 電機工程學系 === 85 === This thesis presents the analysis and design of a charger/
discharger usedin a solar panel supplied lighting system. The
objective is to investigatethe electrical characteristics of the
typical maintenance-free lead-acidbattery. Based on the
characteristics, we develop a 500W charger and discharger.
Proper compensators are designed for governing their dynamics so
that the overall system can have good stability margin. In
addition, protection circuits, such as over current protection,
over temperatureprotection and over voltage protection, are
considered and designed in toprevent the system from damage
during abnormal operation. The charger anddischarger integrated
with the lighting system, is described in detail. Thecomputer
simulations and experimental results are provided to verify the
theoretical discussions.
