The synchronous mode is widely used in the start-up of a position sensorless PMSM drive system. However, the shock in speed and current may occur when the control mode is changed to the position sensorless control mode for a wide-range load. In this

We present a three-phase PWM converter without AC voltage and AC current sensors. The phase angle used in the control system is adjusted by using a PLL controller without sensing AC voltage. To prevent overcurrent at startup, the initial phase angle

In an AC-DC-AC motor drive system, a beat phenomenon of the motor current occurs, especially in the over-modulation range with DC-link voltage ripple and low frequency carrier. We analyze this beat phenomenon and propose two beatless control methods.

We propose a low-cost high-power-factor three-phase rectifier with a turn-on current suppression circuit. With the proposed suppression circuit, standard rectifier diodes can be used instead of fast-recovery diodes in the main diode bridge even with

In this paper, a new ACR (automatic current regulator) scheme is introduced for brushless DC motors. It consists of a model closely resembling the motor and PWM inverter, an assumed rising pattern of the current, and a parameter estimation. Using the

An applicative and embedded-friendly improved dead-time compensation method has been developed. Basic concepts of the proposed method are based on the error time between phase voltage commands and each phase actual output voltage. The error time can
