Innovative Cap Dump Circuit with Automatic Cut-Off | Solar & Wind Power Companion
Welcome to another exciting video! Today, I'm showcasing a unique cap dump circuit with an automatic cut-off feature, perfect for those interested in renewable energy systems like solar and wind power.
This circuit is designed to prevent overcharging by automatically shutting off when your battery reaches the desired voltage. It features a blue LED for charging, a red LED for dumping the capacitor, and a green LED to indicate a full charge. With a power input of almost 15 volts at 1.5 amps, the circuit boosts the voltage to 30 volts using a cost-effective DC-DC converter, charging a 63-volt, 44,000 µF capacitor bank. When the capacitor bank is fully charged, it dumps the energy into the output terminals at 24 volts and 4 amps.
What's fascinating about this circuit is its ability to freeze and safely keep things from overcharging when the output is disconnected, and then resume operation once reconnected. This feature also applies when disconnecting the boost converter.
I've been searching for a circuit like this for a long time, and now, I plan to convert this design into a printed circuit board and make it available for sale. This is my way of helping those who wish to experiment with this experimental tech, especially for maintaining a battery bank in solar or wind energy systems.
