摘要：

In order to increase the power density of the three-phase AC-DC converter, this paper presents a weight optimization method, which considers taking advantage of generator inductance. The optimization method analyzes the interdependence of all the constrains and design parameters, and studies the relationship between the weight of major components and the frequency. The key design parameters include power device, inductance, capacitance and heat sink. The weight estimation model of capacitor and heat sink to frequency are established. The optimal switching frequency to achieve highest power density is evaluated. Therefore, the high power density converter can be obtained.
