چکیده مقاله:
In this paper, a soft switched high frequency ac link converter is studied as an alternative to dc link converters. The proposed configuration overcomes the disadvantages of dc link converters and offers an efficient, light weight, reliable converter with unity power factor and low current total harmonic distortion (THD). It employs 12 bi-directional switches interfacing with a partially resonating ac link consisting of an inductor and a small capacitor in parallel. The capacitor produces soft turn-off under all operating conditions, and the control method guarantees zero voltage turn-on of the switches. As a result of its near zero switching power losses, this converter is capable of operating at high frequencies, which will result in smaller link inductor and filter elements. These characteristics make this converter an outstanding alternative to dc link converters. This paper will evaluate the performance of the proposed converter in the context of several potential applications .
