“…Further, it is given that the working period of PPL usually ranges from tens of milliseconds to seconds [4,18], i.e. the switching period of V L would be longer than 10 −2 s; however, the working period of buck converter, which equals to the switching period of V T , is usually shorter than 10 −3 s. Thus, when V T and V L are turned off and the current i o = 0, the charge saturation on C f is easily formed so that the inductor current i Lf is intermittent, i.e.…”

“…12b, the period T s has an influence on the computation time for the proposed PPL model, especially when T s <10 ms; because the lower T s is, the larger computing consumption for the switching function will be. Fortunately, in most cases, the T s of PPL is larger than 10 ms [4,18]. Therefore, from a trade-off perspective, the computation time for the proposed model is affordable.…”

“…In the primary power source charge stage ( T ch0 or T ch1 ), the instantaneous disturbance source are three kinds of d U /d t and one kind d i /d t disturbances in the primary charge source which are generated by the power diodes and converter switches [6 ], and the caused communication disturbances are shown as I in Fig. 3.…”

“…In the communication network, full duplex RS422 communication mode (differential transmission) is employed, as it shows good qualities such as high speed, long distance and high reliability for transmission. However, intensive electromagnetic (EM) radiation and conducting disturbances are generated from the circuits of the main pulse compression subsystem during different working stages [6 ]. The RS422 communication cable network is severely threatened by the disturbances generated from the Tesla pulse driver itself.…”

“…At present, as to the disturbance source from the Tesla pulse driver itself, some studies focused on the spark gap radiation [8][9][10][11][12] and the charge power source interferences [6]. These studies only paid attention to a special type of interference in a special working stage, however the other interferences in full time domain and full space domain were neglected.…”

The communication circuit network is widely employed for signal transmission in high‐voltage pulse driver system, for commanding, controlling, measurement & communication. The electromagnetic compatibility of the communication circuit network mainly decides the stability and reliability of the high‐voltage pulse driver system. Aiming at the electromagnetic interference (EMI) problems of the RS422 communication circuit in the Tesla pulse driver, the generated disturbance sources and characteristics from the Tesla pulse driver itself are analysed in five divided work stages, and two typical simplified EMI coupling modes for the communication circuit are also presented in this Letter. In the RS422 communication cable circuits between the subsystems of the pulse driver, the time‐domain resonant characteristics of the communication signal and the conducting disturbances are analysed. The error and failure modes of the RS422 communication data caused by the full time‐domain conducting interference are also revealed. Evaluation and calculation method for the time‐domain resonant probability and the interference probability of the RS422 communication signals is also put forward. The communication interference probability is also calculated under different repetition work modes of the Tesla pulse driver. In view of the time‐domain resonance phenomenon, some effective ways for time‐domain resonance elimination and interference compression are put forward.

Extricating the energy from lightning impulse is very difficult for researchers due to the uncontrollability of hazardous and intermittent parameters. This paper proposed a mathematical method to island the lightning impulse to provide safety for the impulse storage system. The proposed model also can intelligently force the impulse to be extricated for the conversion system of the lightning energy storage device. This islanding controller is designed to increase the efficiency and safety of the storage system. Six essential parameters, that is, breakdown voltage, current dependency, spark channel radius, spark channel conductivity, coil inductance, and coil voltage, are considered to design the mathematical model. These parameters are formulated to record the responses of the proposed controller. All the equations are validated by using state of the art experiments and prototype hardware setup. The proposed method, mathematical model, and analyzed responses may assist lightning researchers in advancing lightning energy harvesting.
