Four quadrant operating Luo-converters

Classical DC-DC converters usually perform in single quadrant operation, such as buck converter, boost converter, buck-boost converter, Cuk-converter and Luo-converters. In industrial applications four-quadrant operation is required, e.g. a DC motor runs forward and reverse in motoring and regenerative braking states. This paper introduces a new converter that can perform four-quadrant DC/DC conversion. Because this converter implements dual-direction energy transference it is a second-generation DC/DC converter. The experimental results verified its characteristics.
