Hybrid Battery Charger Circuit

The nominal voltage is circa 235vdc which can peak at 250vdc.

Hybrid battery charger circuit.

Make sure that it is above 18 volts. Z1 z2 3v or 4 7v 1 2 watt zener diode. We have now shipped more than 75 units. R1 r2 r3 r5 r6 10k.

Double dc input hybrid charger circuit. Op amp ic1 is used as a simple voltage comparator. Our specialty is custom charger units. 60hz 50hz 200vac you name it.

Contact us for details. Connect the circuit to the battery with correct polarity and adjust vr till led lights. Red leds 2nos. Opamps lm358 or any similar.

2 shows circuit for the hybrid solar charger which is built around a 12v 10w solar panel connected at sp1 operational ampli fier ca3130 ic1 transistor bc547 t1 12v single changeover relay rl1 step down transformer x1 and a few other compo nents. Parts list for the solar wind dual hybrid battery charger circuit. D1 10 amp rectifier diode or schottky diode. The charging discharging current will be no more than 1 5a i want to use an arduino uno to modulate mosfet s using the controller via pwm to charge the main hybrid battery.

This indicates the conduction of zd2 and output voltage. The diode d1 provides reverse polarity protection and capacitor c1 buffers voltage from the solar panel. Circuit and working fig.
