Current Source Inverters

Current source inverters (CSIs) have the boost function, but they are not widely applied in industrial applications. Therefore, they are not well discussed in the literature. We have carried out an investigation and obtained the output voltage, which is higher than the input voltage.

4.1    Three-Phase Full-Bridge Current Source Inverter

A typical three-phase full-bridge current source inverter is shown in Figure 4.1 [1,2].

The carrier-based pulse width modulation (PWM) technique is applied in this three-phase full-bridge CSI. The main objective of these static power converters is to produce AC output current waveforms from a DC current power supply. Six switches S1 – S6 are applied and switched by the PWM signal. ...
