In the photovoltaic (PV) field, the three-level T-type inverter has largely been accepted as a promising candidate. However, it suffers from the leakage current problem, which can well be addressed by the modified LCL filter. Nonetheless, this modification brings a new challenge of common-mode resonance current (CMRC). To deal with this issue, several CMRC suppression control strategies have been proposed. In high-power applications with low-switching frequencies, the conventional CMRC suppression control strategy becomes invalid, and hence the system stability degrades. To resolve this problem, this paper introduces a delay compensated CMRC (DCCMRC) suppression scheme. In this paper, the simplified model of the modified LCL-filtered T-type inverter is derived. Later, a delay compensation method is proposed to eliminate the unfavorable effect of the digital control delay. Finally, the efficacy of the proposed methodology is validated through a set of simulations and experiments.
