Abstract	In this paper a parameter determing method of digital controller is proposed for spreading capacitance load range more and improving transient characteristics for inductance load. In the previous proposed controller, the configuration of the controller is the same to all loads. At inductive load, there is a possibility that the transient characteristics may become bad and the specification may not be satisfied. Therefore, a load current is estimated at inductive load, and the controller which also uses load current for feedback is configured. A DSP is implemented to this digital controller. It is demonstrated from experiments that the digital controller of which parameters are determined by the proposed method satisfies the given specifications.
