Abstract: This study proposes a Current Source Inverter (CSI) consists of double-tuned resonant circuit at the source side for boosting the input voltage with low Total Harmonic Distortion (THD) which may suitable for microgrid applications. This proposed current source double-tuned inverter overcomes the drawbacks of conventional CSI by reducing the losses and space. Harmonics at the DC side input voltage is attenuated by the construction of double tuned circuit. The double tuned CSI with different control topologies are designed and simulated using MATLAB/Simulink.
