摘　　要：相对输入电压,相位和幅值可控电压调节器(voltageregulator with controllable phase and amplitude,VRCPA)能够分别连续地调节输出电压的相位和幅值大小。该文研究VRCPA输出电压相位及幅值与前后两级占空比各控制参数的优化关系,前级调节输出电压的相位,后级调节输出电压的幅值。提出了2种相位控制参数的优化动态选择方法,2种方法所依据的参数选择曲线在参考相位角处相交,具有相同的初始控制参数。方法 1需调节2个独立的控制参数,而方法 2只需调节1个独立的控制参数,因此相比于方法 1,方法 2简单、易行、控制稳定性高。由此构成VRCPA的控制策略,研制一台单相VRCPA原理实验样机,实验结果与理论分析一致,证明了控制策略的可行性。Compared with the input voltage,the phase and amplitude of the output voltage are regulated respectively by a voltage regulator with controllable phase and amplitude（VRCPA）.Its relationship with the optimization of two duty ratio control parameters of VRCPA was researched for the phase and amplitude of the output voltage.The phase is regulated in the front-part,and the amplitude is regulated in the back-part.For phase regulation,two methods were proposed to select optimal control parameters dynamically.The Curves followed by two methods are crossed at the reference phase angle and have same original control parameters.It is necessary to adjust two independent control parameters for method 1 and one parameter for method 2.So method 2 is simple,easy to implement and has high control stability in comparation with method 1.The control strategy of VRCPA was presented and a prototype of single-phase VRCPA was manufactured.The experimental results verified the correctness of the theory and the feasibility of the control strategy.
