The anomaly detection and prediction of spacecraft power system is an essential factor in determination of the spacecraft health status. This paper proposed a Hidden Markov Model (HMM)based approach to the problem. Health status set was first established according to expert knowledge and operation experience. Model parameters, health index and baseline were then designed for HMM. Probabilities of...
The add-on battery pack in plug-in hybrid electric vehicles can be charged from an AC outlet, feed power back to the grid, provide power for electric traction, and capture regenerative energy when braking. Conventionally, three-stage bidirectional converter interfaces are used to fulfil these functions. In this paper, a single stage integrated converter is proposed based on direct AC/DC conversion...
