| Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 90 === This thesis presents the results of design, implementation, and simulation of an autonomous self-excited induction generator (SEIG) feeding an isolated load through the employment of power converters (rectifier and inverter). The DC-to-AC inverter employs pulse-width-modulated (PWM) technique and a TMS320F240 digital signal processor (DSP) to convert variable-voltage and variable-frequency voltage generated from the SEIG to a three-phase constant-voltage and constant frequency voltage source.
The three-phase induction machine model based on an a-b-c reference frame is employed to simulate the performance of the SEIG connected to the power converters and loads. An experimental prototype with a 2.2 kW induction machine driven by a brushless DC machine (BLDC) is to demonstrate the performance of the proposed control scheme. Both simulated and experimental results of the studied system under different values of loading resistance and rotor speed are accomplished and compared in detail.
It can be concluded from the simulated and experimental results that the proposed power converters with adequate control scheme can effectively improve the performance of output voltage of the studied SEIG under various rotor speeds and loading conditions.
