| 摘 要： | 该逆变器基于正弦波脉宽调制(SPWM)技术，主电路采用三相双极性逆变桥式电路，控制电路采用数字集成电路，编出的数据表并存储于EPROM中，用这些数据来控制每对逆变管的导通与截止，实现将汽车内的直流电压变换为电压、频率可调的三相正弦交流电压，带动三相交流异步电动机。电路简单、实用、造价低，保证三相位的对称性，形成较好的三相正弦波。

| Abstract: | Based on sinusoidal pulse width modulation (SPWM) technology, the main circuit of the inverter adopts the contravariant bridge circuit of three-phase and double-electrode.The control circuit adopts digital integrated circuit. According to this principle,the compiled data list is got,and the datum are written into the EPROM.These datum can control the contravariant pipe passing through and cut-off,and changing DC voltage into three-phase sinusoidal AC voltage of different frequency and different volue inter automobile is realized.Then three-phase AC motor is driven.This electric circuit is simple , practical and cheap.It can make the symmetry of the three phases,shape the better three-phase into reality. |
