In this paper, a Pulse Width Modulation (PWM) based integrated control structure has been proposed to address the limitations of an Interleaved Current-fed Switched Inverter with “n” phases, such as, unequal current distribution among the interleaved phases and the presence of second harmonic ripple in the passive elements. The proposed controller actively reduces the second harmonic component of inductor currents leading to reduced passive component sizing and also ensures equal current sharing among the interleaved phases. The behavior of the proposed control method has been verified using PLECS- based simulation model, and also using a laboratory prototype for proof-of-concept validation.
