The pulse magnetic system shall be consisting of Capacitor discharge type magnetizer system (CDTM) that generates a pulse of magnetic field with a peak value of about 5 Tesla (5T) in the cylindrical fixture. The system will be used for the magnetization of large size ceramic and NdFeB magnets (90mm diameter). Series resonant topology is used for capacitor charging applications. The capacitor charging power supply (CCPS) will charge a 330 mF capacitor bank from 0 V to 450 V in 10 min exhibiting a charging power of 55.68 watts. The amplitude and waveform of fixture current and magnetic field produced in magnetic fixture is obtained from PSPICE simulations and also from experimental measurement.
