Three-phase dual-active-bridge (3p-DAB) converters are widely applied in various medium-to-high power applications due to their low output current ripple and high-power density. However, their high-efficiency and reliable operation still require further investigation. In this paper, an efficiency-oriented optimization and fault-tolerant control method …

In aircraft on-board power supply applications, the wide input frequency brings obstacles for three-phase buck rectifier (3ph-BR) when handling unbalanced input voltages, causing the problem of double-frequency pulsation on active power. To address this issue, an input voltage proportional feedforward control with …
