... and C2 converts the ac. Voltage to a pulsing square wave signal. The square wave is fed to a comparator 1, R3 and Zener diode, Z1 set a reference voltage. When the reference voltage is greater than the sampled output. Voltage, the comparator swings to negative causing comparator (1) to pass the output from the oscillator to its output. The frequency switches transistor (T1), which drives transistor T2, powers the transformer. The transformer induces the EMF across the transformer output. The output is rectified by D1 and filtered by L1 and C3. When the output voltage is increased the sampled outputs increases causing the comparator(2) output to swing to positive which disenables comparator(1), switching off T1 and T2.

Anteprima della tesi: SOLAR SYSTEM CONTROLLER
SOLAR SYSTEM CONTROLLER LITERATURE REVIEW AND PROJECT ANALYSIS 0. INTRODUCTION With most of Kenyans in rural areas without electricity, many people have opted to using solar system for their day to day use. And due to changes in climate conditions and weather, we find that batteries might over charge and sometimes undercharge. For this reason, I have decided to come up with this project to try to charge the battery evenly all the time. This circuit will ensure the output voltage to the battery is always 12v even if the solar output is greater than 12v. This will be achieve by use of a d.c. and a.c. converter. The system will also stop the charging when the battery is full. The system will be affordable since it will be constructed with very few materials which are already in the market. The system will be efficient since it employs a feedback which will help to correct any errors. The ...... and C2 converts the ac. Voltage to a pulsing square wave signal. The square wave is fed to a comparator 1, R3 and Zener diode, Z1 set a reference voltage. When the reference voltage is greater than the sampled output. Voltage, the comparator swings to negative causing comparator (1) to pass the output from the oscillator to its output. The frequency switches transistor (T1), which drives transistor T2, powers the transformer. The transformer induces the EMF across the transformer output. The output is rectified by D1 and filtered by L1 and C3. When the output voltage is increased the sampled outputs increases causing the comparator(2) output to swing to positive which disenables comparator(1), switching off T1 and T2. This makes the output voltage reduce and the process continues to achieve a constant stable output.
