Abstract
- Abstract This article proposes a method to effectively suppress second‐harmonic current (SHC) of dual active bridge (DAB) converter, which adopts the triple‐phase shift (TPS) modulation strategy, in two‐stage single‐phase inverter system. Load current feedforward control with twice the output voltage frequency notch filter inserted is introduced to ensure the dynamic response performance. The averaged model of the system is established to analyse the influence of output impedance of front‐end DAB converter on SHC from the perspective of impedance. The proposed method does not need to consider the accuracy of the intermediate bus capacitance. Finally, an experimental prototype was established to verify the correctness and effectiveness of the proposed SHC reduction method.
