PROJECT TITLE :

Modified Boost Derived Hybrid Converter: Redemption using FCM - 2017

ABSTRACT:

Boost-derived hybrid converter (BDHC) could be a single-stage converter that produces each dc and ac output voltages. The operation of BDHC beneath continuous conduction mode is satisfactory. But, the nonzero discontinuous conduction mode (NZ-DCM) and standalone ac operation prohibit the stable operation of the converter. To mitigate these limitations, changed BDHC (MBDHC) is proposed during this paper. The main idea behind these changes is to redeem NZ-DCM by forced continuous conduction mode (FCM). The adverse effect of NZ-DCM in a very BDHC is analyzed in terms of ac output voltage total harmonic distortion, and dc output voltage ripple. This analysis is more extended for MBDHC to focus on the advantages of FCM. Moreover, for hybrid masses, the efficiency of MBDHC is compared with its counterpart BDHC and cascaded boost inverter.
