Abstract. In the key areas of safety, the safety requirements of the software are becoming higher and higher. However, there are all kinds of safety testing methods, or the presence of state space explosion, or the test case is huge, and the safety testing efficiency is low. In order to solve this problem, this paper proposes a safety testing method, which is based on FAPM model. Getting danger of hazardous events which is through using dynamic fault tree analysis. And it is based on the call graph of the program to build the mapping relationship between basic events and operation, operation and code. Then, build a scene using a Markov model. According to the model generation of safety test case, and according to the test stop criterion to judge the adequacy of the testing.

“…In our experiments, a 2nd order band-pass filter tuned to the line frequency provided an improvement of the line current waveform as long as the line frequency is constant. In systems with varying or "wild" frequency [7,8], good filtering may be problematic, and one may have to use a phase-locked loop or other solutions suitable for varying frequency.…”

“…The emulated capacitance is constant over the range of frequencies (frequency-invariant) if HQ(s) is defined by (7). This is important in applications with varying line frequency such as future aircraft power systems [7,8]. The phase plot shows that, if HQ(s) in (7) is implemented with the negative sign, the admittance phase will change its sign as well (dotted line), and the converter will emulate an inductance at any given frequency.…”

Reactive power source capability allows active-frontend converters with average-current-mode control to be used as reactive power compensators in addition to their primary function as ac-dc converters. Reactive power control in these converters can be realized in multiple ways by adding a suitable controller to the current control loop. The paper presents a comprehensive study of reactive power control realizations in a single-phase AFE converter, along with their merits and limitations, including susceptibility to the ac line noise. Different forms of the reactive power controller are derived in a systematic way by using a closed-loop dynamic model of the converter. Theoretical analysis and simulation results are verified by experiments.

A multi-resolution control strategy is proposed for a DSP-controlled 400Hz Active Power Filter(APF) to reduce the real-time computational requirements. In this manner, the current loop bandwidth is extended for better harmonic compensating performance. By rearranging the computational elements into high and low computational groups, the proposed control strategy takes best advantages of the DSP computation resources to increase the control frequency for the high computational group. Based on the control bandwidth, analysis is presented in determining the sampling frequency for the low computational group. A 20kVA prototype is setup to verify the validity of the proposed strategy. Experimental results show that the proposed control strategy achieves good current compensating effects and dynamic performance.
