Sun Battery Charger Circuit
The above picture is sun battery charger circuit.Electronic filter (VT5) and regulating diode,VD3 constitute regulating circuit.Its stable voltage is used as benchmark voltage of A2 reverse phase input terminal.Measuring battery voltage of resistance R1,R2,R3 and RP1 are added to A2 phase input terminal. When it is lower than benchmark voltage,A2 outputs low PWL,VT3,VT1 and VT2 conduct.If the sun battery voltage is higher than the backup battery voltage,it begins to charge the backup voltage.A1 test sun battery voltage is lower thsn backup battery voltage,A1 outputs low PWL.G3 and G4 are harmonic oscillators and it produces 15 ms pulse every 15s.A1 compares backup battery voltage and the sun battery voltage,for example,VT1 and VT2 is still in cut-off condition if sun battery is lower than backup battery.
