The unified modeling method and double loop controller design of the bi-directional three-level converters are proposed in this paper. The drawbacks of the conventional system are the complex controller configurations due to the different current paths at the duty boundary of 0.5. It makes hard to design double loop controller at previous researches. The unified modeling method which can applicable to full duty ratio is proposed in this paper. The systematic analysis method enables double loop controller design very easily. The controller gains are obtained by the MATLAB automated gain tuning and verified by the PSIM circuit-based program. It can be seen that the waveforms are exactly matched to the design specifications and thus the designed controller can be applicable to the commercial systems.
