If we want to convert 12V DC to 220V AC, we often use the inverter composed of input interface voltage starting circuit, DC conversion circuit, feedback circuit, lc oscillation circuit and its output circuit load, etc. to solve the problem of the shoes and most of all.

Inverter is a kind of direct current into alternating current an electrical conversion equipment, modern inverter using PWM or pulse width modulation to work. The inverter increases the voltage of the DC supply and reverses the current by converting it from a unidirectional flow to an alternating flow. Widely used in various fields of life

If a 12V AC is converted to 220V, the turns ratio of the primary and secondary coils in the transformer in the inverter has to be 1:19. This process involves the knowledge of electromagnetism. After the oscillating circuit converts the DC to AC, the coil boost converts the irregular AC to square wave AC, and finally from the square wave to sinusoidal AC. In the whole process there will also be a filter circuit to filter out garbage signals, thus playing a role in removing impurities.

Summarize: by the inverter bridge, logic control, filter circuit composed of three major components of the inverter, through the lc oscillation circuit and other means of transmitting dc power boosting process, will be converted to 12v dc family commonly used 220v ac. At the same time home general use of the inverter also has a self-protection function, when the inverter temperature is too high or that the current is too large will be self-protection.
