“…SVPWM and SPWM are two AC control methods in common use. The SVPWM technique has mostly been used in the vector control of threephase AC motors or in servo systems due to its superior performance in spite of complexity, and it will be further accepted in the future [1][2][3]. The three-phase reference voltage synthesizes space vector voltage in the plane.…”

In this paper, a method of combining modified space vector control (SVPWM) and sinusoidal pulse width modulation (SPWM) control has been proposed for the threephase permanent magnet synchronous motor (PMSM). This method solves the problem of the torque ripple when the motor starts running and the hardness to control zero axis component when use SVPWM control method. The proposed method uses SPWM control method when the motor starts running or low speed to ensure the stability of the zero axis component of the control system, and utilize the SVPWM method when the motor at high speed to ensure the stability of the torque ripple of the system. So the method made full use of the advantages of SVPWM and SPWM method respectively. Dynamic response and power quality performance are comparatively analyzed for this method. This method uses PI-IP control structure to further improve the robustness of the control system and the response performance. The simulation and experimental results show the dynamic response of the control structure. In order to guarantee the validity of the data, utilize a high precision identification system to guarantee the precision of the parameter used in control system. This paper gives a detailed description of how to use the method mentioned to realize the PWM output and the control structure used. This method is more efficiently and generates less harmonic distortion when compared with traditional method. Index Terms -space vector PWM (SVPWM); sinusoidal pulse width modulation (SPWM); proportion -integration (PI) and integration -proportion (IP); identification system

This paper discusses the operation of the Bi-Polar Synchronous Rectifier (BPSR) a special purpose low frequency amplifier topology. Energy conversion through an output transformer is done a t a frequency much higher than the desired operating waveform frequency. An active rectifier demodulates the switched waveform passing only the desired low frequency waveform to the load. This feature can lead to substantial size and weight reduction in the amplifier. as transformer magnetic volume decreases with increasing frequency. The technology allows full low frequency Class-D amplifiers to be realized with comparable efficiencies, but with much higher power densities.
