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。
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 μs edge,less than 5% overshoot,less than 100μs 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.
