Design of Multilayer Winding-Based Halbach Array PM Compulsator

Abstract

Compulsator provides higher energy density and comparable power density for pulse power supply than capacitor-based sources. With the added feature of natural current, zero-crossing capabilities make compulsator the ideal choice for pulse power supply to electromagnetic launch applications. A multilayer Halbach array permanent magnet (PM) compulsator is designed to achieve the desired performance. The multilayer winding arrangement is considered to minimize the self-inductance and to maximize the short-circuit current capability of the compulsator. Thus, different winding configurations with series and parallel connections in the compulsator are presented in detail. The mathematical modeling of the designed compulsator is also presented in brief. The designed compulsator is simulated by considering temperature rise, PM demagnetization effect, and so on. The designed compulsator performance in a dead short circuit of all phases and with single-phase short-circuit condition is presented. The obtained results show that the designed compulsator achieves the target objective.
