Pwm control of dual active bridge: Comprehensive analysis and experimental verification

Reactive Power and Soft-Switching Capability Analysis of Dual-Active-Bridge DC-DC Converters with Dual-Phase-Shift Control

“…It shows that the efficiency improvement using the DPS is not as good as expected. The effect of the DPS in in terms of efficiency improvement is also undervalued in other studies [6], [8], [19], [20]. The possible reasons may include:…”

Comprehensive steady state analysis of bidirectional dual active bridge DC/DC converter using triple phase shift control

“…Among these are the modulation schemes [5][6][7], converter losses reduction [8][9][10] and modelling of the converter characteristics [11][12]. The first proposed conventional phase shift (CPS) modulation scheme [13] operates the converter bridges with full square waves while controlling the phase shift angle between them in order to determine power transferred.…”

“…Dual phase shift (DPS) modulation [6] aims to reduce the converter reactive power, increase overall efficiency and during power up, suppress the transformer inrush current but has a limitation of some suboptimal modes [7]. Pulse width modulations (PWM) control of DAB converter has been investigated in detail by [7], whereby using hybrid combinations of CPS, single PWM (SPWM) and dual PWM (DPWM), the authors have shown an improvement in low power operation of the converter in wide input output voltages, extension of ZVS range, reduction of peak and RMS currents and further reduction of the transformer size.…”

“…In [8], DAB converter using PWM modulation was introduced and shown an extension of ZVS. Triple phase shift modulation was studied by [7,[14][15][16][17] to further enhance the performance of the converter in terms of improving ZVS range and reducing the overall losses by introducing an extra control variable. In [14], TPS was introduced to study the stability of DAB converter.…”
