Output Filter

The working capability and cost of four-switch three-phase (FSTP) shunt active power filter (APF) are determined by the parameter selection. Based on mathematical model of FSTP inverter, the effect of key parameters, such as dc-bus voltage level and capacitor voltage transform is analyzed. On account of ac output filter inductance, voltage and capacitance on dc side, output filter in the design of four-switch three-phase APF, this paper expounds the optimal selection approach of parameters, sets up simulation model in PSIM, correctness of the method is verified by simulation on the basis of analysis about law of effect.

Shim Coil

It is necessary to develop a high homogeneous, low power consumption, high frequency and small-size shim coil for high precision and low-cost atomic spin gyroscope (ASG). To provide the shim coil, a multi-objective optimization design method is proposed. All structural parameters including the wire diameter are optimized. In addition to the homogeneity, the size of optimized coil, especially the axial position and winding number, is restricted to develop the small-size shim coil with low power consumption. The 0-1 linear programming is adopted in the optimal model to conveniently describe winding distributions. The branch and bound algorithm is used to solve this model. Theoretical optimization results show that the homogeneity of the optimized shim coil is several orders of magnitudes better than the same-size solenoid. A simulation experiment is also conducted. Experimental results show that optimization results are verified, and power consumption of the optimized coil is about half of the solenoid when providing the same uniform magnetic field. This indicates that the proposed optimal method is feasible to develop shim coil for ASG.
