| Research Abstract |
The purpose of the research is to develop the switching power supply with high efficiency and fast transient response. Only by applying a capacitor in series with the switching device, a high efficiency in wide range of the load was realized. A proposed hysteretic PWM method for switching converters provides excellent dynamic performances without increasing control devices and theoretical guideline for designing is also provided. In addition, a high efficiency and fast response converter for mobile power supply were developed.
