A Modulation Method to Realize Sinusoidal Line Current for Bidirectional Isolated Three-Phase AC/DC Dual-Active-Bridge Converter Based on Matrix Converter

Review of Dual-Active-Bridge Converters With Topological Modifications

“…Fig. 27 shows the circuit configuration of a matrix DAB converter in [163]- [171]. They are used in V2G applications [163], [170], distributed generation systems [164], [165], energy storage systems [166], [167], and battery chargers [168]- [171].…”

Duty-Cycle Dependent Phase Shift Modulation of Dual Three-Phase Active Bridge Four-Port AC–DC/DC–AC Converter Eliminating Low Frequency Power Pulsations

“…Based on these observations, the number of required coefficients can be reduced and the remaining coefficients determined. With (17) and due to the symmetry of the D3ABC (i.e., the primary and secondary sides can be swapped without changing the circuit), a 1 = b 1 , a 2 = b 2 , and a 4 = b 4 must hold true. Furthermore, the function of ⟨p⟩ is intended to be symmetric around the operating point D 1 = D 2 = 0.5, since maximum power can be transferred there, which leads to a 1 = b 1 = 0.…”

“…is obtained. Note that P Σ,max represents the maximum power that can be transmitted between primary side and secondary side through the three DAB converter stages of the D3ABC, using (13) (with a 4 = b 4 = 0) and the maximum modulation indices at the two ac ports as defined in (17). Thereby it is irrelevant whether the power transmitted over the galvanic isolation is supplied by the ac or dc port (e.g., of the primary side) or whether the load being supplied is connected to the ac or dc port (e.g., of the secondary side).…”

“…Examples of documented rectifiers with integrated galvanic isolation are the current-fed rectifiers with integrated LLC resonant converter described in [11] or with a DAB converter presented in [12], the rectifier with integrated full-bridge dc/dc converter presented in [13], the rectifier with integrated three-phase DAB converter explained in [14], or the nine-switch converter with integrated three-phase resonant converter described in [15]. These topologies are complemented by further rectifier topologies with integrated galvanic isolation, but without a primary-side dc voltage port, such as matrix-type converters [16], [17] and Swiss-type converters [18], [19].…”

Design and Implementation of Periodic Control for a Matrix Converter-Based Interior Permanent Magnet Synchronous Motor Drive System

“…Since 2020, an increasing number of researchers have focused on modulation methods and predictive controller design for matrix converters. For example, Shigeuchi et al proposed a modulation method for matrix converters to achieve zero-voltage-switching and sinusoidal line currents under bidirectional operation with PQ control [15]. Lei et al investigated a simple modulation scheme with zero common-mode voltages for matrix converter-based PMSM drive systems [16].…”
