Two AC/AC regulators studied in a comparative way: the serial AC link regulator and the boost/inverter converter

This paper presents a comparison of two AC/AC voltage regulators. The AC/AC serial regulator is compared with the conventional AC/AC regulator that uses a rectifier, a boost pre-regulator to obtain unity power factor, and an inverter circuit to obtain an AC voltage in the load. The principle of the operation, theoretical analysis and experimental results are provided.
