Block diagram, Operation
The inverter is known as current source inverter when the input of the inverter is a constant DC current source.
CURRENT
SOURCE INVERTER (CSI)
The
inverter is known as current source inverter when the input of the inverter is
a constant DC current source. Stiff current is supplied to the CSI (current
source inverter) from the DC source where the DC sources have high impedance.
Usually, a large inductor or closed loop-controlled current are used to provide
stiff current. The resulting current wave is stiff which is not influenced by
the load. The AC output current is completely determined by the states of
switching devices in the inverter and the DC applied source.
The
output voltage and current waveform of the inverter circuit, v and i
respectively, are assumed to be AC quantities. These are stated in terms of RMS
values normally while the deviation of these waveforms from their fundamental
and sinusoidal components is represented in the terms of THD factors. THD shows
the total harmonic distortion.
