Car Power Inverters´ Circuit diagrams and work Principle
If you want to operate an electronic device in a vehicle with an 220V AC electric source, it usually takes a 12v DC to AC power inverter. This power inverter converts the DC electricity into AC by using an electronic circuit. You need to have this inverter device on your vehicle in accordance with the required maximum load.
Car Power Inverters Ideal Model:

Here is a 12V power inverter that can use a car battery as a source. DC to AC Power Inverter can be used to handle load up to a maximum of 100W using 10A CT step down transformer. When required a larger load capacity, you can customize the type of transistors on the final power, and capacity used transformer.
Inverter Circuit Diagram:

• There are two parts of car power inverter´s circuit. Each part adopts a TL494 or KA7500 chip to consist a circuit. The function of the first part of the circuit is to convert 12V direct current which is supply by car storage battery to 30 kHz-50 kHz, 220V alternating current through the technology of PWM switch power. The function of second part is to convert 30 kHz-50 kHz, 220V alternating current to 50Hz, 220V alternating current.
• Car power inverter can be divided into sine waveform output and square wave output from the waveform. The sine waveform output a kind of alternating current which is same with the current we use in our daily life. It is suitable for all kinds of LD load. But on the other hand, the structure of circuit is kind of complicate, and the size is large. Nowadays all car power inverters adopt the simulation of sine waveform scheme. It is better than the square waveform. It can induce LD load. Besides, it has lots of advantages, including small size, lightweight, efficient conversion, stable voltage output, high reliability, and a perfect protection system.

• 1.Make sure that the power consumption of the devices is lower than 300W. It can be more durable if you keep the power consumption of the devices less than that of inverter.
• 2. Switch the screw cap of the wiring terminal, and put the wires with annulus on the red or black wiring terminals according to the color respectively, twist screw cap tightly then make sure that wiring terminal contact well with the metal annulus.
• 3. Fix the red clip on the positive side, and fix the black clip on the negative side of storage battery. Do not fix them on opposite side. Or the fuse will burn-out under the protection of inverter after energization. In this case, the fuse should be replaced then restart.
• 4. Replacing fuse: open the fuse box and put a fuse of the same size instead.
• 5. Switch on the button of the car power inverter, and it will work if the indicator light turns from red to green. Then put connector plug into connector socket and switch on the button.
• 6. The car power inverter can protect itself automatically if there is something about overload over-current overheating and short circuit. At this time, the green light will turn off and there is not voltage output any more. Restarting needs disconnection of the inverter and power supply and energization again. When there is something about under-voltage or out of voltage, the red light and green light both turn off and issue "tick tick" alarm sound. The car power inverter will recover working automatically after voltage comes back normally.
• 7. Pay attention to cooling down and away from heat source moistness and dust when using this product. Avoid putting something heavy on it.
• 8. When the city stops electric supply, storage battery will supply power instead. On the contrary, storage battery stops supplying when the city continued to supply electric. This process operates automatically.

• 1.What are car power inverters?
  Power inverter (car inverter) is a device that can convert the DC12V to AC220V and serves for the universal electrical equipment.
• 2.Will car power inverter be accepted widely in and abroad?
  This device is popularly accepted by consumers abroad for their high rate of using cars. When they drive out, they can use this device to connect car´s storage battery which drives electric equipment and tools to work when in the occasion of no alternating current.
• 3.Is car power inverters only used in car?
  Car power inverters are not only used in car, but also used in other occasions as long as there is DC12V. Transforming the DC12V to AC220V easily brings your life great convenience.
• 4.How does car power inverter embody its function of alarming high or low voltage and turning off?
  The red LED turns on with alarm sound when car power inverter was in high or low voltage and in the condition of turning off.
• 5.What is the protective function of car power inverter to battery?
  When the battery voltage reduces to 9.5V, the car power will turn off automatically to make sure the car can work normally, so that battery won´t be damaged.
• 6.What do you need to check out when there are shutting off or warnings in the operation?
  A. Does the power of the electric devices surpass that of the inverter?
  B. Make sure that inverter is connecting well with battery and devices.
  C. Check out the reason why inverter stops working. If the reason is about temperature, restart using it after a break.
• 7.What do you need to pay attention when you are using power inverter?
  A. Do not use electronic devices which power consumption is higher than 150W without a break to avoid fault.
  B. Avoid using the product for a long time when the car engine is shut off,or it may cause trouble because of the low voltage.
  C. Stretch this product from the cigarette lighter after switching off the power.
  D. Stretch this product from the cigarette lighter after using it.
  Please observe the instructions strictly.
