碩士 === 明新科技大學 === 電機工程研究所碩士在職專班 === 103 === This thesis is focusing on the development of an energy recovery system to be used during the burn-in tests of power electronics products before they leave the factory. In the traditional method, long-term burn-in tests employed resistors, inductors, and capacitors as loads to ensure the stability, performance, and reliability of power electronics products. It may result in a substantial amount of energy consumption and create a lot of heat. This means that expensive air-conditioning equipment is needed to remove the generated heat, leading to the profoundly increase of the investment cost of manufacture factories and power transmission equipment. The problem will be significantly mitigated if the electric energy supposed to be consumed on the load can be recovered and sent back to the publicly electric power-supply grid. In this thesis, the system using an electronic load to recover the electric energy across the electric power-supply grid is designed in a modular manner. The main function of the system is to recover part of the electric energy back to the electric power-supply grid through an energy recovery system during the burn-in test. The power dissipation of burn-in testing equipment could be adjusted by the user so as to make an effective use of the electric energy of this system and hence to reduce power consumption cost and achieve the reuse of renewable energy. The resulting system architecture is verified to be feasible through the integration of the system and a practical application.
