The main parameters of several common switches are as shown in Table 1.2. In the pulsed power system, the high-current pulse is generally characterized by high current peak, short rising time and descent time. The main pulse is barely long but changes rapidly.
In the pulsed power system, the high-current pulse is generally characterized by high current peak, short rising time and descent time. The main pulse is barely long but changes rapidly. In this case, pulsed current measurement is one of the key pulsed power technologies, Fig. 1.3 shows the following diagram of pulsed current measurement system.
The pulsed power supply consists of an adjustable DC voltage power supply, E1, a filtering current-limiting inductance, L1, a resonant energy storage capacitor, C1, a feedback diode, DT, of the fast switching thyristor, D1, and a resonant circuit L2 which composes of resonant inductors.
It constitutes the main body of the pulsed power device, as in almost all parts of the pulsed power device are included. The main feature of high-power pulsed power supply is the slow accumulation of energy at a rather low power before the instantaneous release of high power and large energy.
There are two types of excitations of high-power electromagnetic pulses: one is to use high-power particle beams to generate high-power microwaves for microwave weapons; the other is to excite suitable loads directly with high-power pulsed power to generate various broad-spectrum electromagnetic pulses.
The variable-excitation power module applies the excitation signal to electrode system based on reference signal from signal control board (or signal generator). Collect and process the excitation signal and response signal of the tested lithium-ion battery, and obtain the EIS diagram.
