What is a car inverter

A Few years ago, the market appeared a very interesting device - car power inverter. Enthusiasts in electronics has long offered a compact homemade solutions that convert low voltage into a higher. However, Serial production of automotive inverter was launched recently. Since such devices are found everywhere-in the markets of radio, in the shops of automobile spare parts and even in the departments of computing. This is not surprising considering the rich opportunities offered by the automotive inverter to its owner. A little later we will return to this point. But first determine the primary purpose of the device.

So the car power inverter is a compact electronic device, the input of which is with car batteries supplied DC voltage standard values (12 or 24 Volts, depending on the version), and output removed the usual 220 V AC. In other words, the electronic circuits produce increasing low voltage to high and is created from the constant current type variable (“reverse” – hence the name). Owners of personal computers, a similar decision may sound familiar, because it is used in devices uninterruptible power supply (UPS). Actually the way it is. The difference is that the UPS circuit may be designed not only for 12 or 24 V, and the voltage of the installed battery or block.

What can be used vehicle inverter? Initially inverters was designed in order to provide the possibility to be powered by a car cigarette lighter low power (100 watts) appliances – razors, tape recorders, etc Car power inverter for laptop can significantly increase the time. Subsequently, the permissible load capacity was increased up to a value of 300W and more. However, such facilities require a separate line from the battery.

Soon the field of use of such devices has grown significantly. It is quite obvious that the car itself for the operation of the inverter, in fact, not needed. It requires only battery. Thus it became possible to make a simple UPS with great work. For comparison: the load is 100 watts “put” 52 A*h battery for 8-12 hours, even "never dreamed" the best store UPS.

Another use case – emergency home lighting with the disappearance of the mains voltage. In addition, at this time, you can optionally power the low-power personal computer or TV, skreiv minutes and hours without light.

Quality vehicle inverter and battery can be indispensable for power supply of the heating wall of the boiler during planned or emergency outages. However, not every inverter suitable for this purpose because of the peculiarities of the formation of sine wave AC output (when selecting you should carefully read the specification).
