Abstract
Bearingless switched reluctance motor has the advantages of switched reluctance motor such as simple structure, high efficiency and satisfactory robustness and also the inherent high radial force for rotor shaft magnetic suspension. In order to meet the requirements of high speed and stable operation for it, the power supply needs to be well designed. A voltage source inverter is commonly used to supply a three-phase induction motor with variable frequency and variable voltage for variable speed applications. A suitable sine pulse width modulation technique is employed to obtain the required output voltage in the line side of the inverter. The principle, hardware circuit and MCU program are introduced. The result shows the power supply satisfies the demand of BSRM. Keywords: SPWM, Bearingless switched reluctance motor, Power supply, dsPIC30F2010, IR2110.
