In one simple inverter circuit, DC power is connected to a transformer through the center tap of the primary winding. A relay switch is rapidly switched back and forth to allow current to flow back to the DC source following two alternate paths through one end of the primary winding and then the other. The alternation of the direction of current in the primary winding of the transformer produces alternating current
Definition: Current Source Inverter is a type of inverter circuit that changes the dc current at its input into equivalent ac current. It is abbreviated as
In Current Source Inverter (CSI), the input side of the inverter is connected to a DC current source and hence, the polarity of the input current remains the same.

Since the DC side must be treated as a current source, a current source type inverter is used for HVDC applications. Thyristors also remain in use in ultra-large inverters.
4.3 Three-Phase Inverter The dc to ac converters more commonly known as inverters, depending on the type of the supply source and the related topology of the power circuit, are classified as
This constant current characteristic is achieved by incorporating a large inductor on the DC side, which acts as a buffer. The CSI''s design focus on controlling current makes it
A Current Source Inverter (CSI) is a device that converts DC current into AC current with a specified frequency and amplitude. It achieves this by maintaining a constant current at the
