| Summary: | 碩士 === 國立臺北科技大學 === 電機工程系研究所 === 100 === This paper uses half bridge converter structure and PWM signal to control DC / DC converter high side and low side MOSFET switches. The proposed technique can achieve bi-direction energy transmission where the battery is charged when an outer source is attached, whereas the battery can also provide stable voltage when a load is attached. In order to ensure both charge and discharge modes can work well, we start from the state equations, derive the error equations, and find controller parameters. Then we can implement battery charge and discharge controller using the same state feedback gains. We use simulation software to verify feasibility and apply the obtained controller parameters on actual circuit to achieve both charge and discharge purpose. This structure is with advantages of simplifying circuit structure and cost reducing.
