The purpose of this thesis is to implement a magnetizer circuit applied to magnetizer, which are used to magnetizing a magnet material. This thesis uses the current source inverters applied to magnetizing circuit, which can provide and control the magnitude, direction and frequency of the magnetizing fixture. Using the soft switching technique, the switching element achieve zero voltage switching through the resonance to reduce switching losses. Three current source inverters are parallel-connected to share the output current and reduce output current ripple with interleaved technique in order to achieve the more accurate control of the output current.
This thesis uses MATLAB/Simulink to build a simulation system. A digital signal processor(TMS320F28335) is employed as the digital controller, which processes the feedback signals from the system to calculate the phase-shift in the signals for the switches of current source inverter and to provide the triggering signals required for the switches of the current source inverter. Both simulation and experimental results are shown in this thesis to verify the validity of the proposed circuit.
