Design of a Novel Controlled Pulsed Width Full-Bridge Topology for Repetitive Pulsed High Magnetic Field

In this paper, a novel full-bridge pulsed power topology is designed at Wuhan National High Magnet Field Center (WHMFC), which could meet the increasing demands about the intensity and shape of the repetitive pulsed magnetic field for scientific research and industrial applications. In this topology, energy storage capacitor bank, capacitor charging power supply (CCPS), full-bridge converter (FBC), forced commutation circuit (FCC), and the magnet (Lm) are included. According to the different operation states of FBC, functions of generating magnetic field, controlling the duration of the magnetic field and recovering the magnetic energy back to the capacitors can be realized. The advantages of this design include: more effective by recovering the magnet´s energy, less cost by no reverse voltage on the energy storage capacitors.
