Then, converters used in the Bearingless Switched Reluctance Motor system were discussed. Because the current in main winding was unidirectional, dual-switch converter was chosen as the main winding converter. In the case of the radial force windings, which demand bidirectional current, half-bridge converter was chosen. Both converters were designed and manufactured. Moreover, assistant circuits (including the driving circuit, the safeguard circuit, the hysteresis current circuit, the PID circuit, the assistant power supply) and the control panel system were designed, and the principles of operation of thes
