Abstract
A three phase rectifier includes n converter modules in each phase A, B, and C, wherein the AC inputs of the n converter modules of each phase are connected together in parallel, and the DC outputs of respective first to nconverter modules of phases A, B, and C are connected together in parallel as first to nsub-combinations of DC outputs. The first to nsub-combinations of DC outputs may be connected together in selected modes to produce a range of total output DC voltage, wherein the range of total output DC voltage is substantially free of double line frequency ripple and the converter modules are implemented without electrolytic output capacitors. The three phase rectifier is suitable for use in high power applications such as electric vehicle fast chargers.
