SOLAR_POWER_OVERCHARGE_PROTECTION
A voltage regulator is connected across the solar cell to prevent damage to the storage battery due to overcharging. A series diode prevents the array from discharging the battery during hours of darkness. The regulator does not draw power from...
Meter check of a diode
Understanding the polarity (cathode versus anode) and basic functionality of a diode is an essential skill for electronics hobbyists or technicians. A diode acts like a one-way valve for electricity, and its one-way nature can be verified using a DC...
Battery-splitter
A common requirement in many systems is to obtain both positive and negative supplies from a single battery. For applications with small current needs, the circuit illustrated provides a straightforward solution. It generates symmetrical output voltages of ±, each equal...
The MicroPower SE
A micro power solar engine has been a goal since my introduction to BEAM Robotics. I believe that if there wasn't one before, there is one now. What I'm presenting to you looks very similar to one of the circuits...
solar flasher
This circuit is a single transistor flyback (Joule Thief) circuit that features a third coil. With it, flash duration and brightness are significantly enhanced, without the need for large value capacitors.
The described circuit operates as a Joule Thief, a type...
mobile phone charger powered solar cell
A mobile phone charger powered by a solar cell power supply is described. This system utilizes a dual comparator circuit that connects the solar panel to the battery when the voltage at the battery terminal is low and disconnects it...
how does power supply regulate its
Most power supplies regulate either their output voltage or current at a constant level, depending on the load resistance relative to the power supply's output voltage and current settings. This can be summarized as follows: To accomplish this, most power...
variable voltage and current power supply
An alternative method for utilizing operational amplifiers (op-amps) to regulate a power supply is illustrated below. The power transformer necessitates an additional winding to provide the op-amps with a bipolar voltage of +/- 8 volts. This negative voltage is also...
The D1 solar engine
The design is simple, tuneable, but no longer terribly useful. This design has a number of weaknesses; courtesy of Wilf Rigter, here are a few:
The provided description indicates a circuit design that emphasizes simplicity and tunability, yet lacks practical utility...
