Abstract
- Highlights • Proposing a stabilization technique for matrix converters. • Proposing a combination of the damping resistor and the input digital filter. • Providing the stability analysis based on the small signal model of the converter. • Presenting a bidirectional power flow control between the main grid and a microgrid. • Definition of the matrix converter stability regions based on the system parameters. Abstract In this paper, the importance of the matrix converter stabilization in bidirectional power flow control is investigated. A stabilization technique for matrix converters based on a combination of the damping resistor and the input digital filter is proposed. The suggested technique is applied to a direct matrix converter employed as an interface between two power sources as the main grid and a microgrid to realize a stable four-quadrant power flow control process. The control method is based on the voltage oriented control strategy using anti-windup proportional-integral controllers. The stability analysis using the small-signal model of the converter is presented and simulated numerically. The proposed stabilization and bidirectional power flow control methods are validated by experimental tests on a prototype. [ABSTRACT FROM AUTHOR]
