  2. 2. ABSTRACT • This single-stage converter, which is, in essence, an extension of the dc–dc buck–boost converter, can be an excellent alternative to dc-link converters. • Being a buck–boost converter, this converter is capable of both stepping-up and stepping-down the voltage. • The link current and voltage are both alternating, and their frequency can be as high as permitted by the switches and the sampling time of the microcontroller. • This eliminates the need for dc inductors or dc electrolytic capacitors, and the main energy storage element is an ac inductor (L). • Moreover, in this converter, galvanic isolation can be provided by adding a single-phase high-frequency transformer to the link. • Therefore, the proposed converter is expected to be more compact compared to the conventional dc-link converter. • The other advantage of this converter is the soft switching of the switches, which is feasible by adding a small capacitor (C) to the link. www.iistechnologies.in
