To meet the application requirements, parts of the permanent magnets are not magnetized directly after production. They have to be magnetized afterwards by application of a high external field which can come from a magnetizer. Therefore, in this paper, a method based on the inverter circuit is proposed. In the method, the inverter is first included to generate a basic square voltage. A voltage intensifier is then utilized to further boost this square voltage. This process is followed by using the designed switching capacitors and natural inductive characteristics of magnetizing coil so that the proposed method can provide large magnetizing current to loads. To validate the effectiveness of the method, a prototype is set up in the laboratory. The hardware tests with the non-magnetic ferrite magnet is made. Test results indicate that the proposed method can generate the required magnetizing current indeed.
