直流调速系统调速优化

Speed Regulation Optimization of DC Speed Control System

近年来随着微型系统与电力电子的发展,电力电子器件广泛的应用,电机控制方式越来越多;较为突出和应用较广的要数斩波调速和变频调速;通过微控系统控制mos管导通与关断可以实现最简单的斩波电路;同样的将电力电子器件搭建成逆变电路再由微控系统控制逆变电路中电力电子器件关断便能实现变频电路。直流调速系统调速有通过改变电压电流来改变电机的转速;但电机的换向还是通过换向器来实现;直流电源通过调速系统控制交流电机便通过交流电源来实现换向,通过改变交流电源的频率来实现电机转速。

In recent years, with the development of micro system and power electronics, the wide application of power electronic devices, more and more electric motor control methods, more prominent and more widely used chopper speed control and frequency conversion speed control; through the micro control system control MOS tube conduction and turn off can achieve the simplest chopper circuit; the same power electronic power electronics. The device is built into an inverter circuit, and then controlled by the micro control system to turn off the power electronic devices in the inverter circuit, so that the frequency conversion circuit can be realized. The DC speed regulation system changes the speed of the motor by changing the voltage and current, but the commutation of the motor is realized by the commutator; the DC power is controlled by the AC power to realize the commutation by the speed control system, and the speed of the motor is realized by changing the frequency of the AC power supply.
