碩士 === 國立海洋大學 === 電機工程學系 === 87 === The standard current loop is modified for a boost converter to eliminate sensitivity of the control - to - output transfer function to the nature and magnitude of resistive load .The modification is derived from the requirement that the dc gain of the control-to-output transfer function with closed current loop remain constant for load changes. An additional term directly proportional to the load current and output voltage，and inversely proportional to the input voltage is added to the current loop . This results in practically invariant loop gains for different resistive loads .
