摘 要: | 采用在静止直角坐标系中构造虚拟正交电路的方法,推导了单相并联谐振变换器在直接正交(D-Q)旋转坐标系中的等效电路,求解了该等效电路的传递函数;通过仿真验证所推导的D-Q等效电路能够准确地代表原变换器电路。基于阻抗匹配的原则,通过D-Q等效电路的传递函数对单相并联谐振变换器的输出LC滤波器参数进行了优化,达到了输出脉冲电压上升沿时间小于50μs、过冲小于5%、调节时间小于100μs和纹波小于5%的预期指标,验证了采用该方法来优化并联谐振变换器输出LC滤波器参数的可行性。

Abstract: | Direct-quadrature(D-Q) coordinate transformation is an effective circuit modeling method which is often used in three-phase circuit equivalent transformation. In this paper, a method which constructs a virtual orthogonal circuit is used to derivate the D-Q equivalent circuit of the single-phase parallel resonant converter in D-Q rotating coordinate. The transfer function of the equivalent circuit is solved. And it is verified that the derived D-Q equivalent circuit can accurately represent the original converter circuit by simulation. Based on this conclusion, by the transfer function of the D-Q equivalent circuit, the output LC filter parameters of a single-phase parallel resonant converter is designed, meeting the output voltage pulse less than 50 s edge, less than 5% overshoot, less than 100 s settling time and less than 5% ripple. It is proved that the method used to design the parallel resonant converter output LC filter parameters is feasible. |
