| Outline of Final Research Achievements |
The purpose of the research is to develop the switching power supply with high efficiency and fast transient response for automobile application in next generation. In order to save fuel or to achieve a low-emission vehicle, energy management system together with power conversion equipment is required. To provide such a power supply with high efficiency and with excellent dynamic performance, an H-bridge converter controlled not only by the voltage feedback to regulate the output voltage but also by double feedforward controls to deal with wide input voltage range and to reduce the transient voltage for load variation was developed. These methods were also implemented by digital control for ease of design.
