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: 许多有用的地理位置，太阳能为动力的水泵是特别有利的偏远地区，那里可能没有常规电源提供地下水。令人印象深刻的CY8C27443微控制器为基础的太阳能水泵控制器采用了混合信号阵列，可控制的三阶段电机驱动经营潜水水泵直接从太阳能电池板。
强大的PSoC微控制器提供了三相PWM生成，信号调理，过电流和短路保护，温度监测，并不断的电压频率控制。此外，微控制器CY8C27443最大的电力来自太阳能电池阵列。这样做的结果是强大的，低成本，高效率的控制器。-Solar Pump Controller
Useful in many geographic locations, solar-powered pumps are particularly advantageous in remote areas, where there may not be conventional power to provide ground water. The impressive CY8C27443 microcontroller-based Solar Pump Controller features a mixed-signal array that controls a three-phase motor drive to operate a submersible water pump directly from solar panels. The powerful PSoC microcontroller provides three-phase PWM generation, signal conditioning, over-current and fault protection, temperature monitoring, and constant voltage-to-frequency control. Additionally, the CY8C27443 MCU maximizes the power from the solar array. The result is a robust, low-cost, highly efficient controller.

Description: This book is intended to be an exposition of the modeling and control of
electric machines, specifically, the direct current (DC) machine and the
alternating current (AC) machines consisting of the induction motor, the
permanent magnet (PM) synchronous motor, and the brushless DC motor.
The particular emphasis here is on techniques used for high-performance
applications, that is, applications that require both rapid and precise control
of position, speed, and/or torque. Traditionally, DC motors were reserved
for high-performance applications (positioning systems, rolling mills,
traction drives, etc.) because of their relative ease of control compared to
AC machines. However, with the advances in control methods, computing
capability, and power electronics, AC motors continue to replace DC motors
in high-performance applications. The intent here is to carefully derive
the mathematical models of the AC machines and show how these mathematical
models are used to design control algorithms

Description: 无功优化IEEE论文With the increased loading of existing power system, the problem of voltage stability
and voltage collapse has become a major concern in power system planning and operation. The

power optimisation. The technique attempts to utilises fully the reactive power sources in the
system to improve the voltage profile and also to meet the reactive power requirements at the
AC–DC terminals to facilitate the smooth operation of DC links. The method involves successive
solution of steady-state power flows and optimisation of reactive power control variables with
