Abstract

This paper presents a bi-directional 42V PowerNet AC-DC matrix converter for automotive power supply systems, replacing the conventional PWM rectifier and DC-DC converter. In the new proposed structure, large DC bus capacitors are no longer needed. The AC-DC matrix converter converts three-phase AC power into the desired output of 42V DC via single power stage. Therefore, the converter has higher energy density than conventional rectifier circuits. A closed-loop control strategy based on indirect space vector modulation is proposed and the validity is verified. The strategy ensures that the output voltage can be regulated tight at different loads and high-quality input current can be achieved.
