Inverter circuit
is a series of electronic functions to change the voltage DC (direct current)
to AC (alternating) voltage. This arrangement generally used to get the ac
voltage corresponding to the voltage electricity (220 volt) by utilizing the
battery or the battery has a voltage of direct current. This series can be
applied on a wide variety of functions ranging from household needs to the
industry.
For the home, for example when the electricity goes out then you can electricity
utilizing accumulator and this series as a replacement for powering all kinds
of electronic equipment such as televisions, tape, computers, refrigerators and
other home electrical appliances. It's just that you can adjust the power level
which can handle by your inverter circuits.
Example usage of
inverter in household tools right now:
Emergency lights,
these lights serve as a backup during power outages. The power used by
emergency lights coming from the battery. The battery can only save dc voltage.
This dc voltage is then made into electric network voltage households i.e. 220
VAC uses a series of inverters. The battery light on the emergency should the
battery charger circuit using in order to save power.
UPS, power tools
this one very important use in offices. UPS serves to prevent power outages
when equipment voltage from electricity outages. So that the computers are
running and are important data processing does not lose data due to a loss of
electrical power. The working principle of the UPS is actually similar to the
basic principles on the use of emergency lights, battery and inverter circuit.
It's just a series of emergency lights on more modest than in the series on the
UPS.
The working principle of a simple inverter on top of that is
utilizing a series of flip-flop as toll stations. The circuits make use of each
of the two transistors, capacitors and resistors. The value of frequency is
determined by the size of the capacitor and resistor. Voltage of the flip-flop
was later raised by using a transformer (transformer).
Components used:
T1 = Transformer CT
Q1 and Q2 = NPN 2N3055 Transistor
C1 and C2 = 68 microfarad, 25 V
R1 and R2 = 10 ohm, 5 watts
R3 and R4 = 180 ohm, 1 watt
D1 and D2 = IN4007
Note:
Use the transistor Q1 heatshink and Q2
Note the dispasion of each component used
Connect the output of the inverter to terminal 9v on the
transformer ct
Output 220 volts from terminal 0 and 220 volts on the output
transformer CT. don't exactly the same 220volt, depending on your input
terminal of 9v transformer ct. in theory, so that the output voltage approaches
the 220volt then the output of the inverter is 9 times the root of 2.
