Setting up a webcam sight illuminator over your laptop's webcam will certainly “enlighten” your online conversations. Instead of using a pull-up resistor to turn the Darlington on, Q3 is configured as a 1mA current source. There are two modes of operation—voltage regulation or current regulation—the current regulator (when in operation) takes precedence over the voltage regulator.
To use the 24V transformer, a voltage doubler rectifier is required to obtain the raw 53V supply. Note: to keep the series regulator from having to dissipate an unreasonable amount of power, the raw DC voltage should be about 10V higher than the maximum output voltage. There is much destructive power here so it is wise to bring the voltage up gradually via an adjustable DC power supply or Variac powering the transformer primary.
When charging a low battery, the regulator will remain in current limit and the voltage will be low until the float charge voltage is reached.

Hi guys, I'm trying to build a high power regulated power supply for a 12v fan (need about 30A at 12V) control and I found a website where such a power supply is discussed. However, I'm not really getting how the voltage regulator is capable of controlling the output voltage without any kind of loop back.
Also, when I put it together I'm getting a .3v drop between each of the stages of transistors, is this normal? Thanks guys, I'm a total beginner when it comes to circuits but I'm trying to learn as this stuff is really interesting.
This circuit is very simplistic, consisting merely of two cascaded emitter follower stages, one with a single MJE3055 and a second with five MJE3055s. Part of the voltage drop you are seeing is due the the Vbe (Voltage base-to-emitter) that you will find in the MJE3055 data sheet.


Since you are observing only about 0.3 volts from base to emitter, I presume that you are not testing at 30 amps into the load.
Another part of the voltage drop you are seeing is due to the ohmic voltage drop in the 1 ohm resistors in series with each MJE3055 base.
All in all, not a very sophisticated circuit, but simple and possibly ok for driving a fan. To obtain reasonably equal sharing of load current between output transistors they should all be from the same production lot so their characteristics are well matched. Thanks for the thorough explanation awright, I had a feeling that's what was going on simply from logically looking at the connections in the diagram. I'm going to alleviate this issue by using an adjustable Voltage regulator, and adjust its voltage from a small PIC to ramp up the output voltage when it's first powered up.
I'm currently working on sourcing a pair of heatsinks for my TO-3 3053, as my proof of concept is mostly working with to-220 (i think) frame 3053s. There may be a much easier and cheaper, and higher performance way to minimize the inrush current to your radiator fan. You'd have to look at the specs for the properly rated device, but I believe the voltage drop of the thermistor inrush current limiter at steady-state would be much lower than with your example circuit, preserving for the most part the fan performance that the engineers selected. Protect your expensive batteries from discharge damage with this mini-sized electronic cutout switch. Most battery-powered equipment provides no mechanism for disconnecting the batteries when they’re exhausted.
Another example is emergency lighting and security equipment designed to be float-charged from the mains. Except for use as a normal Battery Charger, this circuit is perfect to 'constant-charge' a 12-Volt Lead-Acid Battery, like the one in your flight box, and keep it in optimum charged condition.
Miscellaneous Circuits - Astable multivibrator, pushbutton clock, random neon flasher, etc.


Even when the voltage drops too low for normal operation, battery drain usually continues until all available energy is expended.
In an extended blackout period, the batteries can be completely drained and may not recover when the mains power is finally restored.
This new design does not supersede the Battery Guardian – at least not when it comes to 12V car batteries.
This is particularly true of equipment designed to be powered from alkaline or carbon cells but retro-fitted with rechargeables. The above circuit is a precision voltage source, and contains a temperature sensor with a negative temperature co?ficient.
Instead, it’s a more flexible alternative that can be used with a wide range of battery voltages. Meaning, whenever the surrounding or battery temperature increases the voltage will automatically decrease. This Battery Charger is centered around the LM350 integrated, 3-amp, adjustable stabilizer IC.
The LM350's 'adjust' pin will try to keep the voltage drop between its pin and the output pin at a constant value of 1.25V.
To prevent that sensor Q1 is warmed up by its own current draw, I recommend adding a cooling rib of sorts.
