Abstract: This paper presents a detailed study on technical points of design, control, stability analysis, and hardware development of a direct matrix converter with power flow control for microgrid applications. The converter is used as an interface between a microgrid AC bus and a variable-frequency load, e.g., an induction machine. The main steps of the converter design include the design of input filter, stabilization, commutation, and protection techniques. Practical guidelines are provided for the direct conversion and transmission of modulation and control procedures to the logic processing devices. Through a detailed study of stabilization technique using damping resistors, the stability region of the converter is determined by using the linearized state-space equations. A prototype direct matrix converter has been developed by the proposed design procedures, and experimentally tested for a variable frequency load.
