碩士 === 國立臺北科技大學 === 電機工程系所 === 102 === The thesis will present a converter with multiple sources for energy harvest of internal combustion engine vehicle. The energy sources include solar panel, regeneration energy during braking and thermal electrical generator. Since these three energy sources have different power rating, a power distribution control method is proposed in this thesis. The proposed power distribution control method can effectively implement power distribution while three input sources operate in the MICs at the same time. The second function is mode switching method. MICs is required to use Thermo-Electrical Generator for main energy source. As output power need is more than TEG standard, mode switching method can operate MICs back to breaking recharge system, and posses power distribution function. The specifications of the converter include: input voltage ranging extends from 16 V to 60 V, output power is around 1.32 kW and output voltage is 12 V. The three-phase control signals are with interleaved control to reduce the output voltage ripple. According to the simulation and the result of experiment, MICs can implement power distribution base on different load needs. When it is full load, output voltage ripple is smaller than 1%, and full load efficiency can achieve 90.08%. Besides, when MICs implement switching-mode technology, the system can effectively operate extra input source according to load needs, or part the input source from system.
