The variable dc voltage source is converted into a variable current source by using inductance L. The current I L supplied to the single phase transistorised inverter is adjusted by the combination of variable
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 uniquely suited for high-power
The CSI is a constant current source which supplies ac to the input, and it is also called dc-link converter in which load current is constant. This article discusses the current source inverter.
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.
This model demonstrates a current source inverter that supports embedded code generation for TI C2000 MCUs. It can be run in both ofline PLECS simulation, as well as in real-time operation.
What is a Current Source Inverter? A Current Source Inverter (CSI) is a device that converts DC current into AC current with a specified frequency and amplitude.
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 CSI and sometimes called a current fed inverter.

The core operation of a CSI is based on the ability to convert a steady current from the direct current (DC) source into an alternating current (AC). It operates by adjusting the frequency and magnitude of
In these type of Current Source Inverter, the controlled quantity is the current in the dc link. The current from the dc source remains constant at the controlled value, irrespective of the load and events in the inverter.
Principle of Operationof Current Source InverterAdvantages of Current Source InverterDrawbacks of Current Source Inverter As the input dc current is controlled, the misfiring or short circuiting of the devices connected in CSI will not be a serious problem.The peak current flowing through the switching devices (transistors, thyristors etc.) is limited to a safe value.The commutation circuits required for thyristors are simpler.
