The invention belongs to the technical field of rectifiers, and particularly relates to a rectifier and a parameter optimization method and device thereof. Acquiring an initial value of a rectifier control parameter, and performing iterative optimization solution on the control parameter by adopting an improved dragonfly algorithm in a value range of the control parameter to obtain a solution set of the control parameter; wherein the improvement point of the improved dragonfly algorithm is that Gaussian and Cauchy mixed variation is applied to the dragonfly algorithm, and the position updating mode of dragonfly individuals in the dragonfly algorithm is improved, so that the exploration of dragonflies is updated and optimized. When the improved dragonfly algorithm is applied, the optimization efficiency is high, the dynamic response speed and the tracking precision of the whole system are improved, and the control parameters can rapidly and accurately track the set reference value. Moreover, when the method is
