A novel inverter design by ROHM and Power assist technology. Link here (PDF)
We employ trans-linked interleaved circuits as inverter circuits that utilize the high frequency switching performance of silicon carbide (SiC) MOSFET, achieving a power conversion efficiency of 99% or more at 5 kW. Since this circuit topology allows a reduction in the inductance of the smoothing reactor, the high efficiency is achieved by reducing the number of windings of the reactor to dramatically reduce the copper loss. This document introduces an example of this novel inverter design.
