Energy system as a key component of stratospheric airship plays an important role in the success or failure of the whole flight mission. Here, the topology of HE-boost SBC converter for airship energy system is deeply studied. Based on the original HE-boost converter, a new HE-boost converter is proposed. By analysing its state space equation and small signal model, it is concluded that the stability of the new HE-boost converter is better than that of the original HE-boost converter. Based on this analysis, the optimal design of compensation network of the new HE-Boost converter is studied to ensure that the converter satisfies the condition of minimum phase system, so as to improve the stability of converter. Here, the theoretical analysis is verified and optimised by means of simulation. The paper builds: circuit, verify the correctness of the theoretical analysis and test, the frequency characteristics of the new HE-boost converter under different input and output conditions, technical index of converter can meet the requirements.
