This paper proposes a switched capacitor based non-isolated zero voltage switching (ZVS) bi-directional dc-dc converter. By implementing a switched capacitor loop, it can provide high step up and step down gain. The converter is operated in continuous current mode (CCM) mode where all the power transistors are soft switched by means of dedicated auxiliary resonant networks. Each network consists of...
This paper proposes a high efficiency bi-directional converter with high power handling capability. Soft switching technique is endowed with all power switches by using an auxiliary unified resonant circuit. Zero voltage switching (ZVS) and zero current switching (ZCS) modes are implemented for all power switches in boost operation. For buck mode of operation, ZVS and ZCS are executed for most of...
The D-STATCOM has been utilized to regulate the voltage to its nominal value by exchanging reactive power with the distribution network. For an effective compensation of the sag and swell, two control approaches, namely the phase angle and modulation index schemes have been utilized. For the former, rapid adjustment in the injected or absorbed reactive power cannot be achieved. Thus, this paper proposes...
