N2 - Transformer rectifier units (TRUs) are widely used to convert variable-frequency ac (VFAC) voltage to dc voltage in the more electric aircrafts (MEA). The dc output of TRU contains frequency-dependent voltage ripples, which significantly degrade the dc-link power quality. To solve the issue, this paper proposes an adaptive dc-link voltage ripple compensation approach that accommodates 360-800 Hz VFAC operation range. The proposed control strategy can be simply implemented on the DC-DC converter that already exists in the MEA power system. Though proper design, the auxiliary voltage ripple compensation can be decoupled with the DC-DC converter basic power-flow control in the frequency domain. Finally, hardware experimental results are presented to validate the feasibility of the proposed method.
