CIRCUIT FOR GENERATING REFERENCE SIGNAL FOR CONTROLLING PEAK CURRENT OF CONVERTER SWITCH, ISOLATED CONVERTER AND METHOD FOR GENERATING REFERENCE SIGNAL FOR CONTROLLING PEAK CURRENT OF CONVERTER SWITCH

摘要

The present invention relates to a reference signal generation circuit for controlling the peak current of a converter switch, an insulating converter and a reference signal generation method for controlling the peak current of a converter switch. According to an embodiment of the present invention, a squarer for squaring an input voltage signal distributed from a primary supply voltage of an isolation converter; A duty ratio calculator that calculates an energy transfer duty ratio to the secondary side; And an operation unit for generating and outputting a reference signal for controlling the peak current of the converter switch from the square signal of the input voltage signal by using the energy transfer duty ratio calculated by the duty ratio calculating unit. Is proposed. In addition, a method of generating a reference signal for peak current control of an isolated converter and a converter switch is proposed.
