A Single-Chip Design for the Three-Phase BDCM System


Article Preview

In this work, we present a sensorless single-chip design for the three-phase brushless DC motors (BDCM) system, and which is implemented by a 0.35um CMOS process. A mixed-signal IC will be accomplished by the implementation of analog circuit and digital circuit in the same chip. Eventually, this chip system includes an analog circuit (Hall signal amplifier), a digital circuit (logic process block), and a frequency voltage converter (FVC) to complete the control & driving circuits. Experimental results are included to verify the proposed scheme.
