Boost and buck topology based single phase AC-DC converters with low THD and high power factor
Kabir, Md Ashfanoor; Abedin, Amina Hasan; Rahman, Dhrubo; Mustafiz, Rubiya Binta; Choudhury, Mohammad Ali A Shoukat (© 2011 Institute of Electrical and Electronics Engineers Inc., 2011)Two topologies of single-phase Buck and Boost AC-DC converters are presented. Instead of using a single phase rectifier followed by a boost dc-dc converter, or using a bridge rectifier with two diodes and two switches, the ... -
A single phase buck-boost AC-AC converter with low input current THD and high input power factor
Abedin, Amina Hasan; Kabir, Ashfanoor N M Enamul; Ahmad, Estiak; Rahman, Dhrubo; Choudhury, Mohammad Ali A Shoukat (© 2011 Institute of Electrical and Electronics Engineers Inc., 2011)Two new topologies of Buck-Boost single-phase ac-ac conversion are proposed. In one of the circuits a bi-directional switch with a single buck-boost inductor is used, whereas, in the other circuit a bi-directional switch ...
