In this paper, multiloop interleaved control (MIC) is proposed, and it is combined with conventional multiloop control and the interleaved pulsewidth modulation scheme. The average behavior of the interleaved three-level switch-mode rectifier (SMR) behaves similar to the conventional boost-type SMR even though two capacitor voltages are imbalanced. It implies that conventional multiloop control can be applied to the interleaved three-level SMRs to achieve the desired power factor correction function. The proposed MIC is digitally implemented and verified in a field-programmable-gate-array-based system. The provided results show that MIC stably works and the capacitor voltages are eventually balanced during the system operations.
