An Ideal DC Transformer for Active DC Distribution Networks Based on Constant-Transformation-Ratio DABC
IEEE Transactions on Power Electronics(2020)
摘要
This paper employs a single-phase-shift modulated dual-active-bridge converter (DABC), and establishes a small-signal model, which involves its voltage transformation ratio. Then, through a voltage transformation ratio feedback loop, which is feedforward compensated by the port voltages and currents, closed-loop control of the transformation ratio of the DABC is realized. The proposed controller c...
