How to Generate Electricity

!±8± How to Generate Electricity

This is a simple science project style demonstration, on how a motor can be a generator. I am using a DC motor that I salvaged out of a Wal Mart toy scooter. It is a permanent magnet motor, and very efficient as a generator. If you were to put a regulator and a DC to AC inverter with it, you could get a usable amount of electricity.

Transistor DC-AC inverter capacity

!±8± Transistor DC-AC inverter capacity

This video shows a DC-AC inverter, which has an output voltage regulatet, and there is no IC is used. The 50 Hz square wave is generated by a 2-transistor oscillator. The 50 Hz square wave is then obtained by the driver transistors, the "guide" of the bridge complete two two TIP122 TIP127 Darlington transistor exists. Thus armed, the bridge passes the full power transformer and alters the polarity - the results of AC and the AC has been strengthenedthrough the transformer. The voltage regulation system mainly consists of a voltage divider and a transistor that "pre-biased" and then gets a negative voltage from the voltage divider. The NPN transistor then amplifies the difference between these stresses and leads to the PNP transistor TIP127, which is reliable, especially for the power that is fed into the transformer. This inverter is not a good efficiency. The transistors get very hot after a few minutes to run the CD-Radio,I have shown. In addition, the input voltage must be at least 6V highest voltage of the transformer ... With a transformer with 18V and 24V input inverter have been able to feed a 230V 40W bulb in its normal brightness, but the pear was "flicker", so do not know if it came from the power supply or inverter. This project is more of a "proof of concept" project that I did, but I soon as the pattern of the converter can be installed again if you want to share. The frequency is...

Solar charge controller for solar panels

!±8± Solar charge controller for solar panels

The photovoltaic modules are the choice of consumers.

With fuel prices fossil rising are companies Fuel Power like coal and oil leaving to generate most their electricity was forced raising prices then homeowners now opting for 'Solar energy to meet their energy needs. Photovoltaic systems are very popular with home owners and apartment, because the energy is free, and recent technological advances have reduced the initial cost of suchSystems.

The batteries require constant charging.

Because of the intermittent nature of solar energy, is not useful devices directly to a photovoltaic panel. Instead, power is through the plates during the hours of sun-charged batteries, where it is stored for use on record upon request. The output of solar panels depends on certain factors such as the position of the solar cells, the time of day and season. All these factors affect the incidence ofSunlight, photovoltaic cells and thus the temperature of the cells. Because these dynamic conditions, variations in the performance of the plates are not conducive to a battery of good health. As a general rule, such as batteries, at a rate that is approximately 20% of their amp hour rating for free. For example, an amplifier 10 would be ideal to calculate a 50 amps hours of battery life. Because the batteries can not fast overload, is a solar charge controller requiredTo ensure the correct charging current is maintained.

What is a solar charge controller and how it works?

A solar charge controller is an electronic circuit, the output voltage and current from solar panels on the needs of the game fits batteries recharged. To charge a battery, charger - or in this case, the solar system - must be uploaded to a potential higher than the battery. In other words, the voltage must be greater than the plateopposite the battery voltage under load to produce a positive flow of current in the battery. But how much more should it be? The current flow is based on Ohm's law: E = I * R, where E is the voltage in volts, I is current in amperes and R is the resistance in ohms is measured. The effective voltage in this circuit, the output voltage of the solar battery voltage less the opposite. We can make a difference in voltagenecessary, our current flow desired by inserting our values lead to the known equation. Assuming a 12 volt battery with 50 Ah capacity, charge current, our goal is to be valued at about 10 amps. There is no resistance in this circuit, with the exception of the internal battery resistance, which is a fraction of the ohms. In this case, we will approach was 0.2 ohms. With Ohm's Law, we multiply 10 amps of 0.2 ohms and get 2 volts as a result. This means that our solar panel must be 2 voltshigher than our battery voltage to obtain our goal to hold a charge. This example shows that the nominal output voltage of the solar panels must be greater than the battery charge controller for solar pay for the job. As mentioned, the current values dynamically, and thus the need for a charge. There are some very sophisticated solar charge controller available today, use the Maximum Power Point Tracking MPPT, or in order to adapt to differentCombinations of battery and the panel as 24V, 36V, 48V, etc. These controllers use DC-DC converter to match the voltage and measure the use of digital circuits for the current parameters many times per second to adjust the power output accordingly.

The charge controller is necessary to correct.

As you can see, is a solar charge controller is an essential part of any PV system. It 'true that a simple charging circuit function can be achieved with fewer parts to buildto save from your local electronics, this option is not recommended for the average person. With so many variables associated with solar energy, is to use a solar charge controller, the ability to monitor all relevant parameters and recommended the optimum cost for the batteries, however. Using a high-quality solar charge controller ensures that you enjoy maximum battery life and the best of your PV system.

Already langmal wanted a video to make it. The development is to die for the inverter shown here. The frequency is 50 Hz (51, lt irgentwas my meter) [may also be available in 1 Hz or 50 Hz for its language, but the issue]. The inverter transformer 30W Dem shown little capacity. Efficiency have not yet calculated, but in full sun and 60W (10W solar modules 6) Easy enough for Heiskleber, welder, Dremel (obviously allsimultaneously). 555 makes the clock, diode / transistor circuit makes Q / Q bar out of it and controls is a MOSFET die. TIP127 TL072 and take care of a relative constant (adjustable) output voltage of 230V. Compared to the previous circuit contact 555 Dem I also spend a potentiometer man advantage with the regular cycle 50/50 Just Can [Increased efficiency]. The advantage of the converter is not running the ER DAS with 12 or 24 (Solar panels provide17.5-21V or so), but for the voltage of the solar modules (this makes the 7812 death Steuerlektronik always has a constant voltage 12V). Form of output rectangle is of course "only", but sufficient for most consumers to die. I have already bought a more powerful transformer, Get well soon build (in the next two months ...)

What does it mean in reality is that the continuous current or 12 volts and 3 amps of power offers. The power supply is the small plastic box (usually black) in the centerthe supply line between the power house and the unit is power.

After a 12-volt DC-3A wrote on your power supply means you can save a lot of energy with the new device you just bought. In the old days it takes for the whole house, electric appliances 110 or more to work properly, but thanks to advances in technology you can now use any type of electronic device cited or electric with only 12 volts. This kind of power is less vulnerable toFire (due to short circuits), and proves to be reliable, offering a great life for the device.
