“…The magnetic scalar potential (Equation ( 13)) in the field was then equivalent to the Kirchhoff voltage equation in the circuit. Figure 3 shows the circuit implementation form of the i-th subequation in (13). The magnetic scalar potential in the field space can be treated as the node potential in the circuit.…”

“…If the traditional method is applied to generate the netlist, a large circuit for n sub-equations ( 13) needs to be drawn in Workview. Through programming, using 'ofstream' head file and loop statements to change the node number, netlists for all sub-equations in (13) were written to the output file. where L is the coil length, N is coil turns, M the number of tetrahedral elements of the magnetic core surrounded by the coil, t is the unit tangential vector of the magnetic core,…”

“…There are some more accurate magnetic equivalent circuit models outside the field of magnetic balance sensors, such as magnetic shielding effectiveness in Rogowski coils [11], transformers [12,13], and switched reluctance motors [14]. However, due to the differences in structure and working-principle circumstances, these models can only be used in their respective fields.…”

In this paper, a field–circuit combined simulation method, based on the magnetic scalar potential volume integral equation (MSP-VIE) and its fast algorithms, are proposed for the transient simulation and nonlinear distortion analysis of the magnetic balance current sensor. The magnetic part of the sensor is modeled and simulated by MSP-VIE with the field matrices extracted by the method of moments. By directly implementing the magnetic field equation in the circuit, these field matrices can be regarded as equivalent circuit parameters of the magnetic part, to construct the corresponding SPICE model. Finally, the field–circuit combined model of the entire sensor is unified in a circuit, so with the SPICE solver, the transient simulation is accomplished in the time domain. Moreover, aiming at the time-consuming problem, this paper presents a corresponding fast method to accelerate the simulation. The comparison of measurement and simulation demonstrates that the proposed method not only realizes the transient simulation of the whole sensor, but also simulates some hidden performance details; thus, it can be applied to practical engineering, to guide and test the early design of the product.

This paper presents the design and test of a gas-insulated linear transformer driver (LTD) cavity aimed at the Z-pinch experimental device CZ-34. The LTD cavity has a diameter of 2290 mm and a height of 346 mm. It consists of 23 main bricks and 1 trigger brick. Each main brick is comprised of two 100 nF capacitors connected electrically in series with a field-distortion gas switch. The trigger brick is comprised of two 50 nF capacitors connected in series with a compact multi-gap gas switch. All bricks are placed in the cavity filled with compressed SF6 and are pluggable like drawers. The trigger pulse generated by the trigger brick passes through an azimuthal transmission line to the trigger ring and makes the main bricks discharge synchronously. The LTD cavity can deliver ∼1 MA current pulse with a rise time of 115 ns to 0.08 Ω liquid resistance load when the charging voltage is ±100 kV, which is in good agreement with the circuit simulation results. Experimental results demonstrate the successful application of using gas insulation and pluggable bricks. The technical feasibility of the charging configuration, triggering method, and isolation resistors is verified. There is little difference in output performance as return-current rods replaced the outside metal cylinder, which provides a new path for the design of LTD cavities in series.
