| Summary: | 碩士 === 國立虎尾科技大學 === 車輛工程系碩士班 === 103 === Current Sharing Control Scheme has been presented in this thesis and applied to a dual Interleave Boost Converter. This technique should be operated under power 100W. Using the interleave converter to make the output load be shared by two booster circuits. But all the parameters for both dual Interleave Boost Converters must be the same. For example, inductance, switches, various of power components , control components, and power consumption. Also the circuit board has to be the same as above-mentioned. It will be certain degree of difficulty in making circuit boards and mass production. Therefore, Current Sharing Control Scheme has added in this thesis, get the current from the output by using a Hall Sensor, through the comparator, differential amplifier, and negative feedback, and then send back each parameter to Dual Interleave Boost Converter Pulse Width Modulation (PWM). When sum up the total of two parameters, the two Dual Interleave Boost Converters will determine how much the Pulse Width Modulation need to reduce or increase. Under any load condition, each converter can share 50% of the load equally. Two sets of Dual Interleave Boost Converter with Current Sharing Control and parallel connected are developed. The output power of the proposed scheme is 140W. It has been confirmed its feasibility, and the experimental results are satisfactory.
