Convertor circuit boards are power electronic devices which converter Direct current (DC) to Alternative current (AC). This board converts 12V DC current to 220V AC current. It works on the frequency of 50Mhz to 60Mhz. It has an onboard step up transformer. This board has inbuilt over voltage, over current, and short circuit protection. The board is perfectly design to provide high output performance. This type of board is use in solar system, to charge the battery of the vehicles, to drive low power AC motors, etc.
