Abstract: In this article, an analog lock-in amplifier (ALIA) based on synchronous in-phase and quadrature (I/Q) demodulation is proposed for wide range capacitance measurement of high accuracy. In ...
Abstract: The rotating high frequency voltage injection (RHFVI) method is widely used for sensorless control of permanent magnet synchronous motor (PMSM) at low and zero speed. The advantage of this ...
