Current stress optimization control of isolated AC-DC matrix converter

Abstract The Isolated AC/DC matrix converter realizes bi-directional energy transmission through phase shift control. existing control schemes do not coordinate the modulation coefficient and ratio well, which will cause large current stress to converter, resulting in low efficiency. To solve this problem, paper analyses working mechanism of IAMC under dual It constructs a mathematical model calculate stress. An optimal method for isolated is proposed. suppressed by coordinating internal external ratio. Finally, simulation platform built verify proposed method.
