Bidirectional AC DC Converter for Regenerative Braking
Electronics ETF, 2012 In this paper, a bidirectional AC-DC converter is analyzed. The converter applies a half‑bridge thyristor rectifier and a recuperating thyristor bridge instead of a braking resistor. Recuperating mode of the converter is focused in the analysis, and it is shown that the converter exposes two operating modes within the recuperating mode, one ...
