A circuit that inverts direct current into alternating current is called an inverter circuit. In a specific case, the same thyristor converter circuit can be used for both rectification and inverter.
When the converter works in the inverter state, if the AC side of the converter is connected to the AC power source, the DC power is inverted to the same frequency AC power and sent back to the power grid, called active inverter. If the AC side of the converter is not connected to the grid and is directly connected to the load, that is, inverting the DC power to an AC supply with a certain frequency or an adjustable frequency, it is called a passive inverter. AC frequency control is to use this principle to work. In addition to the DC reversible speed control system, the active inverter is also used for the cascade speed regulation and high voltage DC transmission of the AC rotor rotor asynchronous motor.
