Ordered Pt3Mn Intermetallic Nanoparticles Supported on Atomically Dispersed Mn–N–C as Electrocatalysts for Fuel Cells

Angewandte Chemie, EarlyView.
Ordered L12‐Pt3Mn intermetallic alloys are uniformly deposited onto atomically dispersed Mn–N–C supports. The synergistic effect between MnN4 sites and Pt3Mn elevates interfacial binding strength and dissolution barriers while favorably weakening *OH adsorption. It delivers exceptional catalytic activity and stability in fuel cells, serving as an ideal

Open-end winding induction machine fed by a dual-output indirect matrix converter [PDF]

, 2016
Open-ended winding induction machines fed from standard two-level Voltage Source Inverters (VSI) provide an attractive arrangement for AC drives. An alternative approach is to use a dual output Indirect Matrix Converter (IMC).

Distributed generation interface using indirect matrix converter in boost mode with controllable grid side reactive power [PDF]

, 2012
Indirect matrix converter (IMC) using two stages configuration is topologically more flexible than 3×3 direct matrix converter (DMC). For grid integration of ac type distributed generators, the ac/ac converters need voltage boost function, which can't be
