Abstract
A DC/DC converter generally needs to work under high switching frequency when used as an adjustable power supply to reduce the size of magnetic elements such as inductors, transformers and capacitors, but with the rising of the switch frequency, the switch losses will increase and the efficiency will reduce. To solve these problems, research is actively being done on a soft switching method that can be applied under high frequency and on a PWM converter that can be applied under low frequency such as a multi level topology. In this project, a DC-DC conversion method for reducing the ripple of output voltage is proposed. In this proposed converter, buck converters are connected in series to generate the output voltage. By using this method, the ripple of output voltage can be reducing compared to a conventional buck converter. Particularly when output voltage is low, the number of acting switching elements is less and the result of ripple reduction is more obvious, it is expected that the converter proposed in this project could be very useful in the case of wide-range output voltage.
