ABSTRACT

Classical DC/DC converters usually perform in single-quadrant operation, such as buck converter and Luo-converters. Multiple-quadrant operation is required in industrial applications, for example, a DC motor running forward and reverse in motoring and regenerative braking states. This chapter introduces three new converters that can perform two-and four-quadrant DC/DC conversion. One particular application is the MIT 42/±14 V DC/DC converter used for new car power supply systems. Because this converter implements dual-direction energy transference, it is a second-generation DC/DC converter. The simulation and experimental results have veried its characteristics.
