Overview of Technology

A novel technology consisting of a universal single-phase and three-phase DC/AC converter

Technology Overview
MSU researchers have created a novel converter topology and control system for application in three-phase and single-phase DG/EV- charger units. The proposed converter consists of six controllable power electronic switches, a DC capacitor, an output filter, and a high-performance multivariable control system. The proposed control system can completely eliminate the DC-bus voltage ripples and non-characteristic harmonics which are the subtle power quality challenges for the existing VSCs.

Benefits

  • The proposed topology is advantageous as it works at a smaller DC capacitor which leads to:
  • Longer lifetime and lower initial and operational/maintenance costs
  • Provides excellent power quality and can be universally designed to operate for both single-phase and three-phase models.

Applications
The existing three-phase inverters may be upgraded readily to achieve the features of this invention. Then, their DC-bus element may simply be removed and replaced with a smaller, less expensive and more durable one.
