【摘要】 根据提出的新型相位幅值控制算法,结合三相PWM整流器的状态空间方程,通过坐标变换和小信号分析推导出以变流器前端电压滞后角ξ作为输入量同输出直流电压Uξ作为输出量的三阶传递函数,并合理简化成为一阶传递函数。通过仿真和实验证明了理论分析的正确性。更多还原

【Abstract】 In the paper a new arithmetic of phase and amplitude control is proposed. The front point voltage lag angle ξ of a rectifier is regarded as input variable and output DC voltage Udc is regarded as output variable. The three order transferfunction of Three-Phase PWM Rectifier is deduced based on the control through coordinate transforming and small signal analysis. It is reasonably reduced to one order transfer function. The simulations and experiments show that the theoretical analysis is correct.更多还原
