Abstract
The powers used in the motor drive system are mostly DC sources like batteries. Even AC powers in some systems are generated from DC sources by the inverter. It is can be forecasted that the DC-link communications will be widely used in various industrial fields. In this paper a novel BLDC motor drive system using DC-link communications is proposed. The characteristic of this system Is that the communication only needs 2 DC lines. There are not additional lines to translate the reference signals. And the reliability o3 the system is ensured especially under some terrible circumstances. The number of lines can be minimized when the DC-link communication method is applied in the multi motor control system and the slip ring design also can be simplified when this method is applied in rotation machines. The proposed motor system is clarified by the PSIM and MATLAB simulations and tested through the hardware prototype.
