碩士 === 國立高雄應用科技大學 === 電機工程系 === 99 === Hybrid power filter is the combination of active power filter and passive power filter. It has advantages of most active power filter and passive power filter. However, the supplied reactive power is a fixed vale and it will not vary with the load change. In this paper, a hybrid power filter with the function of variable reactive power compensation is developed. The method of variable reactive power compensation is based on the step change of capacitor sets. So, the compensated reactive power can be changed under different load, and it can also avoid the evident lagging or leading of the utility current. Computer simulation is carried out to verify the function of the developed hybrid power filter. The simulation results show it has the expected results.
