Analysis and design of switched-boost inverter in CCM, DCM and BCM operations

This paper proposes a comprehensive analysis of switched boost inverter's (SBI) voltage and current equations, using specific switching method in continuous current mode (CCM) operation. The presented switching method makes SBI proper to be used in galvanic and electrochemical applications. The boundary amount of inductor between the two CCM and discontinuous current mode (DCM) operations is calculated and also the operative parameters are determined. In addition, the diodes' and switches' voltage and current stresses, the inductor's current ripple and the capacitor's voltage ripple equations are represented which are needful to design the components. Moreover, the switching control circuit is proposed. Finally, the PSCAD/EMTDC software program results are given to show the theoretical analysis validation.
