成果简介	NOVELTY - The system has an analog circuit provided with a first comparator and a second comparator for generating gate pulses (14) to drive switches of converters. An analog circuit introduces a relative time shift between gate pulses and adjust duty ratios of the gate pulses by changing duty ratio controlling reference voltages applied to first and second comparators resulting a relative phase-shifted triggering of the switches for simultaneously minimizing ripples in currents through the inductors of the converters. The analog circuit operates inversely coupled inductors of the converters and generates relative time shifted gate pulses to minimize inductor current ripples due to inductor current slopes of inversely coupled inductors for four operating states of the switches. USE - System for decreasing inductor current ripples in single-input multiple-output direct current (DC)-DC converters. Uses include but are not limited to fuel cells, photovoltaic generation systems, uninterrupted power supplies and electric traction. ADVANTAGE - The system reduces inductor current ripples in DC-DC converters by adjusting duty ratio controlling reference voltages to the comparators. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for decreasing inductor current ripples in CI-SIDO converter. DESCRIPTION OF DRAWING(S) - The drawing shows a circuit diagram of a system for decreasing inductor current ripples in single-input multiple-output DC-DC converters. 12DC output voltages 14Gate pulses 15Gate pulses 30Common DC input voltage 31Common input voltage terminals
