Equalization Technique for Balancing the Modulation Ratio Characteristics of the Single-Phase-to-Three-Phase Matrix Converter

Abstract EN

Three-phase system has numerous advantages over the single-phase system in terms of instantaneous power, stability, and cost.

Three-phase systems are not available in every location particularly in remote rural areas, hill stations, low voltage distribution homes, and so forth.

Having a system that is capable of converting directly the readily available single-phase system to three phases will have greater usability in various applications.

The routine techniques adopted in the direct ac-ac single-phase-to-three-phase converters do not yield the best desired outputs because of their complexity in the segregation process and bidirectional nature of the input signal.

Other initiatives use ac-dc-ac converters which are huge and costly due to dc link energy storage devices.

Further, none of these systems provide a convincing result in producing the standard three-phase output voltages that are 120° away from each other.

This paper proposes an effective direct ac-ac single-phase-to-three-phase conversion technique based on space vector pulse width modulation based matrix converter system that produces a convincing three-phase output signals from a single-phase source with balanced modulation index characteristics.

The details of the scientific programming adopted on the proposed technique were presented.
