These studies in the thesis have been done as follows : it is proved that if the three - phase single - switch boost type power - factor - correction can work in continuous - current - mode , its power factor can not reach unity . therefore , it is not qualified for high power and high requirement application . according to the ac side equivalent circuit of the three - phase three - switch boost type power - factor - correction , the equations to realize unity power factor have been deduced and realized by integrate - reset - control circuit 本论文把积分复位控制成功应用于三相功率因数校正技术中,作了以下几方面的研究: 1 .从理论上证明了三相单开关boost型pfc即使工作在ccm ,其功率因数也不能达到1 ,在大功率和对功率因数校正能力要求较高的场合,三相单开关boost型pfc达不到要求, 2 .根据三相三开关boost型功率因数校正交流侧的等效电路,推导出实现单位功率因数所需的控制方程,并用积分复位控制电路进行实现,在理论研究的基础上进行了仿真研究。
