摘要: The harmonic disturbance that is caused by the double line frequency ripple power in single phase AC/DC or DC/AC system. This issue can be eased through installation of bulky electrolytic capacitors dc-link. Unfortunately, such passive filtering approach may inevitably lead to low density and limited system lifetime. Symmetrical full-bridge circuit uses dc-link absorb power. In this paper presents a symmetrical full bridge which utilizes dc link. Capacitors additional pair switches small inductor. By implementing four switches, we reduce capacitance as 22µf/400volt. Also help PI controller switching stress reduced with stable DC link voltage. As result, objectives high-efficiency conversion obtained.
