| Abstract |
This paper investigates the utilization of a
buck-type current source rectifier as an active front-end
stage for an AC/AC converter for applications that require
adjustable step-down DC-link voltage with improved upper
voltage limit robust to unbalanced voltage supply and
additionally eliminating the low-frequency common mode
voltage from its dc-link voltage. The proposed solution is to
add two asymmetric H-bridge inverters in series with each
of the DC-side terminals of the buck rectifier to allow
injection of differential and common mode voltage in order
to achieve the above goals. |
