Dynamic Evolution Control Method for Isolated Half-Bridge Three-Level DC/DC Converter

A dynamic evolution control for an isolated half-bridge three-level DC-DC converter is proposed in this paper. The dynamic evolution control forces the error state of the control plant to follow a specific path to ensure that the error state reaches zero with the increase of time, in which only two control parameters are needed to be adjusted, it has advantage in less mathematical calculation, and it is suitable for digital control. Compared with many other traditional control method, fast dynamic response can be obtained by using dynamic evolution control. In this paper, the dynamic evolution control method is employed to an isolated half-bridge three-level DC-DC converter, the simulation and experimental results are provided to verify the correctness of the theoretical analysis and the effectiveness of the control strategy.
