Description: 使用V/F原理的交流电机控制和简单的PWM算法
交流电机在连接到电源时只能以其额定速度运转，所以要改变转速必须改变电源频率。本篇应用文档展示了这些技术如何在AT90PWM3上简单的被实现，也说明了AVR RISC微处理器在电源控制方面的应用。-Induction motors can only run at their rated speed when they are connected to the main power supply. This is the reason why variable frequency drives are needed to vary the rotor speed of an induction motor. The aim of this application note is to show how these techniques can be easily implemented on a AT90PWM3, an AVR RISC based microcontroller dedicated to power control applications.

Description: The ever-increasing reliance on electronic devices which utilize AC power highlights the problems associated with the unexpected loss of power from the electrical grid. In places where the electrical infrastructure is not well-developed, brown-outs can prove fatal when electronic medical instruments become unusable. Therefore, there is a need for inexpensive and reliable pure-sine wave inverters for use with medical devices in the underdeveloped world. This report documents the development of one component of an uninterruptible power supply, the DC-to-AC inverter. Through the use of analog signal processing techniques, a prototype which efficiently and accurately emulates the pure-sine wave power present on the power grid was created. The three-level PWM system within this report is created with the possibility of a feedback-regulated system to be implemented in the future.

Description: Variable speed drives with Pulse Width Modulation are increasingly applied in many new industrial
applications for more efficient performance. Recently, developments in power electronics and semiconductor
technology have lead to widespread use of power electronic converters in the power electronic systems. A number of
Pulse width modulation (PWM) schemes are used to obtain variable voltage and frequency supply from a three-phase
voltage source inverter. Among the different PWM techniques proposed for voltage fed inverters, the sinusoidal PWM
technique has been popularly accepted. But there is an increasing trend of using space vector PWM (SVPWM) because
of their easier digital realization, reduced harmonics, reduced switching losses and better dc bus utilization. This paper
focuses on step by step development of SVPWM implemented on a PMBLDC motor. Simulation results are obtained
using MATLAB/Simulink environment for effectiveness of the stud
